500+ Octopus Names: Cute, Clever, and Downright Fascinating Ideas

An octopus is one of the only pets you can own that might actually be smarter than you expect it to be — and that alone earns it a name better than “the octopus.”

Whether you’re naming a pet octopus in a home aquarium, a favorite resident at your local aquarium, a plush toy, or just a character for a story, octopuses inspire a specific kind of naming enthusiasm that other sea creatures don’t quite get. Maybe it’s the eight arms. Maybe it’s the fact that octopuses can solve puzzles, open jars, and apparently recognize individual people — traits that make them feel less like “fish” and more like a genuinely distinct personality waiting for a Vampire Names to match.

We pulled together more than 500 octopus names for this list, because most lists online repeat the same 40 or 50 names under a dozen different headers — cute becomes funny becomes creative with barely any actual new material. We wanted this one to go deeper, so you’ll find dedicated categories for mythical and legendary names, ocean and marine-themed names, color and physical-trait names, famous pop culture octopuses, and a full reference section on names with real meanings behind them.

We also dug into where octopus-naming culture actually came from, since that context tends to get skipped on other lists entirely, and it’s more interesting than you’d expect once you know it.

Whether you’re naming a real pet octopus, an aquarium favorite you visit often, a plush toy, or a character in a story, there’s a name in here that fits. Let’s dive in and get started.

   History & Background of Naming Octopuses

Octopuses have had a strange relationship with human naming culture for a very long time — mostly because, for most of history, they weren’t something people got close enough to name at all. Ancient Greek and Mediterranean cultures certainly knew octopuses well as food and as subjects of myth, but the idea of an octopus as an individual with a name and a personality is a much newer development, tied almost entirely to how recently we’ve understood just how intelligent they actually are.

That shift really took off in the last few decades of marine biology research, once studies started documenting octopuses solving mazes, using tools, and even appearing to recognize specific aquarium staff members. Once octopuses started being treated less like invertebrate curiosities and more like genuinely clever animals with distinct behaviors, aquariums and researchers started giving them names instead of specimen numbers — a shift that mirrors, in a much smaller way, how primates and dolphins went from being studied anonymously to being named individuals once their intelligence became undeniable.

Pop culture picked up the thread from there. Movies, documentaries, and viral aquarium videos gave the public a much closer look at octopus behavior than most people ever got in person, and names followed naturally once octopuses started feeling like characters rather than just animals. A documentary octopus with a distinct personality and a name is a completely different cultural object than “an octopus” in the abstract — and once that door opened, pet octopus keeping and octopus-naming culture online exploded right alongside it.

The home aquarium hobby pushed things even further in the 2010s and 2020s, as octopus keeping — while genuinely demanding and not for beginners — grew into its own dedicated corner of the reptile-and-exotic-pet-adjacent hobbyist world. Online octopus-keeping communities developed their own naming conventions fast, often leaning into either scientific-sounding names that nod to the animal’s intelligence, or completely absurd puns that play off the “eight arms” joke in as many ways as possible. Care sheets, escape-proofing tips, and feeding schedules all got shared right alongside naming conventions, since the hobby grew almost entirely through word-of-mouth and forum posts rather than mainstream pet store guidance.

  A Few Famous Octopuses, and the Names Behind Them

  What Makes a Great Octopus Name?

●  It matches the octopus’s actual personality, once you know it

Octopuses have famously distinct personalities — some are bold and curious, others are shy and reclusive. Give it a little time before locking in a name, since a Archer Names like “Houdini” only really earns its keep once you’ve seen the octopus attempt an escape or two, and plenty of first-time owners are surprised by just how quickly that kind of behavior shows up once the animal settles in.

●  It plays with the number eight, but doesn’t overdo it

Eight arms is the single most obvious thing about an octopus, and it’s fair game for naming — “Ocho,” “Eighty-Eight,” “Octavia” all lean into it lightly. Just be careful not to make every single name in your shortlist an arm-count pun; one clever nod is usually enough.

●  It’s easy to say daily, for the life of the pet

If you’re naming an actual pet octopus, keep in mind most species have fairly short lifespans compared to other pets — often a year or two. Even so, you’ll say this name constantly during that window, so pick something you’ll enjoy repeating rather than something that gets old by week three.

●  It has a story or reference behind it

The best octopus names usually connect to something — mythology, a favorite documentary, a pun about intelligence or camouflage. A name with a story behind it tends to be more fun to explain than one picked completely at random.

●  It doesn’t rely purely on “squishy” or “gross” jokes

Octopuses get a lot of names built around slime, ink, or general sea-creature ickiness, and while a few of those land well, leaning on that theme too heavily can undersell just how genuinely striking and intelligent these animals are. Balance the gross-out humor with something that also reflects the octopus’s cleverness.

None of this needs to take long to sort out. Most people land on a name within the first day or two of actually meeting the octopus, usually once its personality starts showing through — whether that’s bold curiosity, shy hiding, or a knack for problem-solving. Use these five checks as a filter, not a formula you need to satisfy perfectly.

   Male Octopus Names

Male octopus names tend to lean into either intelligence and cleverness or a bit of mythological drama — think names that would suit a puzzle-solving escape artist as easily as a legendary sea monster. Below is a set with real meanings behind them, followed by a longer list of raw options.

  Male Octopus Names with Meanings

  More Male Octopus Names

A quick note worth knowing if you’re naming a real pet octopus: most common pet species, like the California two-spot octopus, only live around one to two years even in ideal conditions. That short lifespan isn’t a reason to skip naming your octopus — if anything, it’s a reason to pick something you’ll enjoy saying for the entire time you have together, rather than something that takes weeks to feel natural.

   Female Octopus Names

Female octopus names often lean into elegance, mythology, or a soft playful sound — think ocean goddesses on one end and cute, bubbly nicknames on the other. There’s also a strong lane of gemstone and color-based Great Warrior Names , since octopuses can flash such a wide range of shades.

  Female Octopus Names with Meanings

  More Female Octopus Names

Sexing an octopus is genuinely difficult even for experienced keepers, since the most reliable method involves examining the tip of the third right arm for a specialized structure used in mating, which isn’t always easy to spot without close observation. If you’re not fully sure which you have, it’s worth treating the gendered name a little loosely, since plenty of octopus owners end up finding out later that their “male” was actually female, or vice versa, without it causing any real issue.

   Cute & Cuddly Octopus Names

Round-bodied, big-eyed, and genuinely expressive, octopuses have a face made for a cute Pirate Names . This category skips the drama entirely and goes for soft, snacky, or just plain adorable.

Cute names tend to suit smaller species particularly well — the dwarf octopus, for instance, can be smaller than a golf ball as an adult, which makes something like “Peaches” or “Nugget” feel proportionate in a way it wouldn’t for a giant Pacific octopus, a species that can span several feet across when fully grown.

   Funny Octopus Names

Eight arms is basically an open invitation for puns, and octopus owners rarely resist. This category leans into the number jokes, the ink jokes, and the general absurdity of an animal that looks like it was designed by committee.

There’s a reason octopus puns land so consistently well compared to other animals: the sheer number of built-in joke opportunities. Eight arms, an ink defense mechanism, a soft boneless body, and a face that somehow manages to look permanently unimpressed — that’s four completely different joke categories available before you even start getting creative.

   Cool & Badass Octopus Names

If your octopus has real presence — a mimic octopus with an intimidating display, or a giant Pacific octopus with genuine size — it earns something with more edge. This category skips cute and goes for tough, sharp, and a little mysterious.

The giant Pacific octopus is probably the species that earns this category most legitimately — it’s the largest octopus species in the world, with some individuals recorded at over 16 feet across including the arms. A name like “Leviathan” or “Behemoth” isn’t just dramatic flair on an animal like that; it genuinely fits the scale involved.

   Mythical & Legendary Octopus Names

Octopuses have a long history of being mistaken for — or blended with — sea monsters in folklore, which makes this one of the most naturally fitting categories on the whole list. These names lean on legends, gods, and mythical creatures with a marine connection.

It’s worth noting that the Kraken itself was likely inspired by real sightings of giant squid rather than octopuses specifically, since the two animals were often confused by sailors encountering something enormous and tentacled in deep, dark water long before marine biology could reliably tell them apart. That technicality has never stopped Kraken from being one of the most popular Fake Country Names for large pet or aquarium octopuses anyway.

   Famous & Pop Culture Octopus Names

📸 IMAGE: A cartoon-style illustration of a friendly octopus character waving with several arms. Alt: Octopus character illustrating famous and pop culture octopus name ideas

Movies, viral news stories, and aquarium fame have given octopuses more recognizable individual identities than almost any other sea creature. Borrowing one of these names means most people will instantly get the reference.

Paul the Octopus remains probably the single most famous named octopus in modern history, having correctly picked the outcome of eight consecutive matches during the 2008 European Championship and 2010 World Cup by choosing between two food-baited boxes marked with competing national flags. Paul passed away shortly after the 2010 tournament, but the phenomenon cemented “naming your octopus like it has real personality” firmly into mainstream pop culture rather than something limited to aquarium staff and marine biologists.

   Ocean & Marine-Themed Names

Sometimes the most fitting name for an octopus is one that just leans into where it actually lives. These pull from tides, reefs, currents, and the general vocabulary of the sea.

Octopuses actually live across a huge range of ocean environments, from shallow tide pools you might spot on a beach walk to the deep sea trenches that never see sunlight — so a name tied to a specific marine environment can double as a nod to where your particular species naturally lives, rather than just being generic ocean flavor picked without any real connection to the animal in front of you.

   Color & Physical Trait-Based Names

Octopuses are famous for changing color and texture almost instantly, which makes this one of the most naturally descriptive categories on the list. These Khajiit Names lean on shade, pattern, and physical feature rather than personality or myth.

Octopuses achieve their color changes through specialized skin cells called chromatophores, which expand and contract to reveal or hide different pigments almost instantly — the process happens so fast that slow-motion footage is often needed to actually see it unfold step by step, layer by layer, rather than as a single instant shift. A color-based name captures something that’s genuinely one of the most visually remarkable things about the entire species, not just a surface-level color match.

   Unique & Creative Octopus Names

If the usual pool of “Inky” and “Squishy” feels too familiar, this category is built for something odder — invented, foreign, or just far enough off the beaten path that you won’t run into three other octopus owners with the same one.

A good trick for generating more names like these on your own: take a real ocean-related word — tide, reef, current, brine — and pair it with a soft invented suffix like “-elle,” “-yth,” or “-vex.” “Coral” plus “yth” becomes “Coralyth.” “Brine” plus “wick” becomes “Brinewick.” It’s a simple formula, but it reliably produces names that sound specific and original rather than pulled straight off another list.

   One-Word Octopus Names

Short, punchy, and easy to yell across the room when your octopus makes an escape attempt — these are the names that work when you don’t want to overthink it, and they’re just as easy to fit on a tank label.

One-word names also tend to work best if you end up caring for more than one octopus over time, or if you volunteer at an aquarium and end up naming several residents informally. Short names sit more comfortably on tank labels and feeding charts than long invented ones, which matters more in practice than it might seem when you’re just browsing a list.

   Quick Facts That Might Influence Your Name Choice

A few genuinely interesting facts about octopuses that tend to come up naturally once you start naming one — not essential, but worth knowing before you commit to something permanent.

None of these facts need to dictate your naming choice, but they’re the kind of details that make naming an octopus feel a little more informed than naming, say, a goldfish — this is a genuinely unusual animal, and a name that nods to why makes the whole thing more fun, especially if you end up explaining the reference to someone visiting your tank for the first time.

   Octopus Names with Meanings

A name hits differently when you know the real word or history behind it. Here’s a reference list pulling from Greek, Japanese, Spanish, French, and other roots tied directly to octopuses and the sea — the kind of names that reward someone for actually asking what they mean.

A handful of these — tako, pulpo, poulpe, piovra — are simply the word “octopus” in different languages, which makes them some of the most versatile and least-explained-sounding options on this entire list. They work well on their own, or as a base to build a longer name from, like “Tako-chan” or “Pulpo Grande.”

   Common Mistakes to Avoid When Naming an Octopus

A few patterns show up often enough among first-time octopus owners and enthusiasts that they’re worth flagging before you settle on a name for good.

●  Stacking too many number-eight puns into one name

Ocho, Octavia, and Eighty-Eight are all great names individually, but combining several arm-count references into one name — something like “Ocho Octavia the Eighth” — tends to feel more exhausting than clever. One clean reference to the number eight is usually plenty.

●  Naming before you’ve seen any real personality

Octopuses show distinct behavior fast once they settle into an enclosure, and a name picked in the first few hours sometimes doesn’t match what shows up after a few days. A shy-seeming octopus locked in as “Bold” or “Fearless” can feel a little off once its actual temperament becomes clear.

●  Underestimating how short the naming window might be

Given how short many octopus lifespans are compared to typical pets, it’s worth picking a name you’re genuinely happy with quickly rather than dragging out the decision for weeks. You’ll get less total time with the name than you might expect going in.

●  Picking something that only makes sense in text, not out loud

Invented names built from clever word-blends can look great written down but turn out awkward to actually say during feeding time or when introducing the octopus to a friend. Testing a name out loud before committing avoids this fairly common letdown.

   How to Create Your Own Octopus Name

  Method 1: Start with the number eight, but use it sparingly

Ocho, Octavia, Eighty-Eight, Octane — there’s a huge pool of names built around the number eight, since it’s the single most obvious fact about the animal. Use one of these as your anchor if you like, but resist the urge to pile on multiple number-eight puns in the same name; one clean reference usually lands better than three stacked together. It’s the same principle as a good pun in general — the first one gets a laugh, the third one in a row starts to feel like you’re trying too hard.

  Method 2: Lean on the species’ most famous ability

Camouflage, ink release, and problem-solving are the three traits octopuses are best known for, and all three make solid naming material. “Camo” or “Chroma” nods to color change. “Inky” or “Inkwell” nods to the defense mechanism. “Houdini” or “Puzzle” nods to their famous intelligence and escape attempts.

  Method 3: Borrow from mythology or a language you connect with

Kraken, Scylla, and Cthulhu all come from mythology and fiction tied loosely to giant sea creatures, and any of them work well as inspiration even for a much smaller pet octopus. Alternatively, the word “octopus” itself translates differently across languages — tako, pulpo, poulpe, piovra — and any of those work as a standalone name with a bit of built-in meaning.

  Method 4: Watch the octopus’s actual behavior before locking anything in

Octopuses show personality fast — some hide constantly, some are bold and curious, some seem to specifically enjoy interacting with their owner. Giving it even a few days before settling on a permanent name means you’re naming the animal you actually have, not just a generic idea of what an octopus should be like.

  Method 5: Say it out loud a few times before committing

Whether you’re naming a pet, an aquarium favorite you visit often, or a plush toy, say the shortlisted names out loud a few times in casual conversation. The one that still feels natural after a few tries is usually the one that sticks — the one that feels forced or embarrassing to say out loud usually gets quietly dropped within a week anyway.

   Frequently Asked Questions

Q: What is a good name for a pet octopus?

A: It depends on the species and personality, but reliable all-around choices include Inky, Otto, Ocho, and Squishy — these work for nearly any octopus regardless of size or color. If your octopus has already shown a clear personality trait, like a tendency to escape or hide, naming around that trait often produces a more memorable result than picking something generic, and it tends to make the name feel earned rather than arbitrary.

Q: What are some cute names for an octopus?

A: Cute octopus names tend to lean soft and snacky — think Squishy, Mochi, Bubbles, Noodle, or Marshmallow. These work especially well for smaller or younger octopuses, since the softness of the name matches the softness of the animal’s body and movement.

Q: What are some funny names for an octopus?

A: Funny octopus names usually play on the number eight or the ink defense mechanism — Ate Legs, Ink Master, Sir Squishalot, and Eight-Ball are all popular examples. The humor tends to land best when the joke is easy to explain in one sentence rather than requiring a long setup.

Q: Are there real meanings behind common octopus names?

A: Quite a few, actually. “Octopus” itself comes from the Greek “oktopous,” meaning “eight feet.” Words for octopus in other languages — tako (Japanese), pulpo (Spanish), poulpe (French) — also work well as standalone names with real linguistic history behind them.

Q: What’s a good name for a smart or clever octopus?

A: Names that reference problem-solving or escape tend to fit best here — Houdini, Puzzle, Cephalo, or Professor Inkling all nod to octopus intelligence specifically, which is one of the most well-documented and genuinely impressive traits of the species.

Q: Can I name my octopus after a myth or legend?

A: Absolutely — this is one of the most naturally fitting categories, since octopuses have been mistaken for sea monsters throughout folklore for centuries. Kraken, Scylla, Cthulhu, and Poseidon are all popular choices that borrow directly from mythology tied to the sea.

Q: Do octopuses actually respond to their names?

A: Not in the way a dog or cat might, but octopuses are genuinely intelligent enough that many aquarium keepers report their octopus recognizing specific people over time, particularly whoever feeds them most often. It’s not quite the same as name recognition, but it’s close enough that plenty of owners feel their octopus knows exactly who’s calling.

Q: How many octopus names are there to choose from on this list?

A: This list includes more than 500 names spread across categories like cute, funny, cool, mythical, famous, ocean-themed, color-based, and unique names, plus a dedicated section on names with real meanings and etymology — enough variety that you shouldn’t need to repeat what every other octopus fan online has already picked.

Q: Is it okay to rename an octopus after already picking a name?

A: Yes, and it happens fairly often. Octopus personalities can take a few days to reveal themselves fully, especially in a new tank or environment, and plenty of owners end up switching a name once the animal’s actual temperament settles in. Given how short many octopus lifespans already are, there’s little reason to stick with a name that doesn’t feel right if a better one comes along.

   Conclusion

At the end of the day, naming an octopus is a small way of acknowledging just how genuinely remarkable these animals are. They’re not just another sea creature — they solve puzzles, change color on command, and occasionally escape enclosures in ways that make headlines. That deserves a name better than “the octopus.”

Don’t stress over finding the perfect one. The best octopus names are usually the ones that make you smile the moment you say them out loud, not the ones you spent a week agonizing over. If a name from this list already made you laugh or nod along, there’s a good chance it’s the one.

And if your octopus’s personality ends up surprising you — the shy one turns out to be the boldest tank-mate around, or the “escape artist” name turns out to be more fitting than you ever expected — that’s completely normal. Octopus owners rename their pets more often than most, simply because these animals reveal so much personality once you actually get to know them.

If you’re still torn between a few finalists, try saying each one out loud during a feeding session, the same way you’d test a name on any other pet you were getting to know for the first time. Whichever one you reach for naturally, without thinking about it, is usually the real answer hiding underneath all the deliberating — and given how quickly octopus personalities tend to reveal themselves, you probably won’t have to wait long to find out.

Whatever you land on — whether it’s something mythological like Kraken, something food-based like Mochi, or something completely invented like Ocholumen — the name is officially official. Go introduce your octopus to the world.

“Eight arms, three hearts, and apparently enough personality to need a name better than ‘it.'”
