So, you’ve got your underwater city all planned out and ready to go. All that’s left is to think of a name for it!

If you’re struggling with ideas or stuck on how to make your underwater world sound like the most amazing underwater world ever, then this blog post might be just what you need.

Check out our list of 32 awesome underwater city names below – hopefully one will suit your needs perfectly.

Cool Underwater City Names

1. Atlantis

This one is fairly obvious – and if you’re making an underwater city in a video game or movie, then it’s practically compulsory to use Atlantis as one of your names.

It has such history behind it that even people who don’t know anything about Greek mythology will instantly recognize the name because they’ve probably seen Disney’s “Atlantis: The Lost Empire” before!

If you want something with just a little more creativity though, we recommend trying out some other underwater cities instead.

Why not try Poseidonis? If nothing else, at least it’ll make all your fellow gamers and readers very jealous because everyone loves Atlantis (and its many secrets).

2. Nereia

This is another classic choice for any serious undersea world-creators out there. It comes from Greek mythology and refers to a sea nymph who resided in the ocean depths – making it perfect for your city’s name if you want something with a bit of an ethereal feel to it.

3. Lemuria

This is another great choice that has its origins in mythology (this time, Hindu mythology).

Lemuria was actually a continent that sunk into the ocean after a cataclysmic event, so using it as the name for your underwater city gives it an air of tragedy and loss.

If that’s what you’re going for then go for it – but make sure your citizens are ready for a dark and stormy existence!

Underwater city

4. Oceania

If you’re looking for something more general than specific mythological names, then Oceania is a great option.

It’s the name given to the hypothetical continent that covers the entire Pacific Ocean, so it definitely has the ‘underwater city’ feel to it.

Plus, it’s easy enough to remember and say that even your non-English speaking citizens will be able to pronounce it without any trouble.

5. Aquaria

This one is perfect if you want your city beneath the waters to have a more ethereal quality about it – after all, Aquarius is often associated with watery themes like rain and rivers.

It also has connotations of freshness and new beginnings, making it perfect for cities that are just starting out on their journey beneath the waves!

6. Cetus

This one comes from Greek mythology once again, and it refers to a sea monster that was slain by Perseus.

If you’re looking for a name with some history and power behind it, then Cetus is definitely the way to go – just make sure your citizens are brave enough to take on whatever challenges lie ahead!

7. Leviathan

Speaking of sea monsters… Leviathan is another great option that’s perfect if you want your underwater city to be shrouded in mystery and fear.

It comes from Hebrew mythology and refers to a giant sea serpent that was said to be so large that its coils could encircle the world. Yikes!

8. Kraken

This one is perfect for any video game or movie-makers out there who are looking for an evil undersea city to unleash on the world.

The Kraken is a giant sea monster that was said to dwell in the deepest parts of the ocean, and it’s definitely not something you want to meet up with if you’re ever lost at sea.

Underwater city

9. Prospero

This one comes from Shakespeare’s play “The Tempest” and it refers to a sorcerer who is stranded on an island after a shipwreck.

If you’re looking for a name that has some literary history behind it, Prospero is a great option – and it also sounds suitably mysterious for an underwater city!
