When I was eight years old, I made up a mermaid name for myself: Aqualina Seawish. I wrote it in purple ink in a notebook and told my best friend it was my “real name” if I ever got a tail. Looking back, I realise I was doing something every creative person does — I was building a world, and that meant giving characters names that sounded like they belonged in that world. Whether you’re writing a fantasy novel, creating a mermaid character for a game, or just having fun imagining underwater kingdoms, the names give you real sources: mythological mermaids, literary traditions, movie characters, and the patterns that make names feel magical. Some of these are names you could give a real daughter; others are purely for play and imagination.
This guide organises 80+ mermaid names by their source: mythological (Greek Nereids, Celtic Selkies), literary (Andersen, Shakespeare), movie/TV (Disney, modern fantasy), and ocean-themed invented names. Each name comes with its meaning, cultural origin, and a note on what makes it sound “mermaid” — whether it’s the flow of syllables, water-related words, or celestial undertones.
Key Takeaways
- Mythological mermaids have ancient names — Greek Nereids (Thetis, Amphitrite), Celtic Selkies (Muirgen), and Norse Merrows have specific etymologies.
- Water words feel magical — Names with “aqua,” “mare,” “nixie,” “siren,” “nereid,” or “undine” signal “mermaid” without being obvious.
- Double-syllable names roll off the tongue — Marina, Coralia, Sirenia sound more mermaid-like than single-syllable names.
- Movie mermaids set modern expectations — Ariel, Madison, Aquamarine become cultural reference points; newer films add Syrena, Namora.
- You can invent mermaid names — Combine water words (aqua, wave, pearl) with feminine suffixes (-ia, -ana, -elle) to create your own.
Mythological Mermaid Names from Ancient Cultures
Before Disney and fantasy literature, ancient cultures had their own water spirits and sea creatures. These names carry real history and were used in religious rites and stories.
Greek Mythology: The Nereids
In Greek mythology, the Nereids are 50 sea nymphs, daughters of Nereus (the old man of the sea) and Doris (an Oceanid). They were worshipped as protective spirits of sailors and fishermen.
| Nereid Name | Meaning | Symbolic Role |
|---|---|---|
| Thetis | Disposer, placer | Leader of the Nereids; mother of Achilles |
| Amphitrite | The third one who encircles | Queen of the sea; wife of Poseidon |
| Galene | Calm sea | Goddess of calm waters |
| Psamathe | Sand goddess | Protector of beaches and shorelines |
| Nerida | Daughter of Nereus | Generic Nereid name; timeless and poetic |
| Leucothea | White goddess | A Nereid deified after death; patron of sailors |
Example: In Homer’s Iliad, Thetis is depicted as wise and protective, comforting her son Achilles when he grieves. Her name carries weight and nobility.
Celtic Mythology: The Selkies
Celtic selkies are seals who can shed their skins and become human. These creatures appear in Scottish, Irish, and Scandinavian folklore as tragic figures — often lured to land by love, or trapped between two worlds.
| Selkie/Merrow Name | Origin | Story or Meaning |
|---|---|---|
| Muirgen | Irish | Born of the sea; became a saint |
| Niamh | Irish | Radiance, luster; took a human lover to the fairy realm |
| Ondine | Germanic/Celtic blend | Little wave; water spirit without a soul (in Germanic myth) |
| Una | Irish/Celtic | White wave; associated with selkies |
| Ronan | Irish/Celtic | Little seal; also a male selkie name |
Cultural note: Celtic selkie stories are melancholy — they often end with the selkie returning to the sea, unable to stay human forever. These names carry emotional depth, not just aesthetic prettiness.
Literary Mermaid Names from Classic Stories
These names come from works of literature, opera, and fairy tales that shaped how we imagine mermaids.
Hans Christian Andersen’s “The Little Mermaid”
Andersen never named his little mermaid directly in the original 1837 tale — Disney changed that to Ariel. But the story introduced the idea of a curious, yearning mermaid willing to sacrifice everything.
- Ariel — Hebrew for “lion of God”; Disney’s choice implies nobility and courage.
- Ursula — Latin for “little bear”; the sea witch villain in Disney’s version (an octopus, not a mermaid, but thematically linked).
- Vanessa — Ursula’s human disguise in the Disney film; uses allure and deception.
German Legend: Lorelei
Lorelei (or Loreley) is a figure from German folklore — a siren-like creature who sat on a rock overlooking the Rhine River, luring sailors to their deaths with her beautiful singing. Her name appears in Romantic poetry and 19th-century literature.
Meaning: “Alluring enchantress” or “murmuring cliff”
Literary feel: Dangerous, seductive, tragic — used for complex, morally grey mermaid characters.
Example: If you’re writing a story where your mermaid isn’t purely good, Lorelei captures that darkness.
Movie and TV Mermaid Names
Modern entertainment has given us new mermaid names that feel contemporary and instantly recognisable.
| Character | Movie / Show | Year | Meaning or Note |
|---|---|---|---|
| Ariel | The Little Mermaid (Disney) | 1989 | Hebrew: “lion of God”; curious, brave, yearning |
| Madison | Splash | 1984 | She chooses this name after seeing a street sign; means “Son of Maud” |
| Marina | Sinbad: Legend of the Seven Seas | 2003 | Latin: “of the sea”; noble and protective |
| Aquamarine | Aquamarine | 2006 | A blue-green gemstone; literally “water of the sea” (Latin) |
| Morgana | The Little Mermaid II: Return to the Sea | 2000 | Welsh: “sea circle” or “shore dweller”; ambiguous, powerful |
| Syrena | Pirates of the Caribbean: On Stranger Tides | 2011 | Greek: “siren”; tragic, vulnerable, hunted |
| Nami | One Piece (anime/manga) | 1997+ | Japanese: “wave”; adventurous navigator mermaid |
Example: Madison’s choice of her name reflects the randomness and joy of becoming human — she saw something pretty and claimed it. That character beats informs how the name feels in modern usage.

Names from Water Mythology Across Cultures
| Name | Origin / Meaning | Why It Sounds Mermaid-Like |
|---|---|---|
| Adira | Hebrew: “strong water” | Combines strength with fluidity |
| Naida | Greek: “water nymph” | Direct reference to mythological water beings |
| Nerissa | Greek: “sea nymph” | Derived from Nereus, father of the Nereids |
| Ondine | French/Germanic: “little wave” | Lyrical sound, poetic meaning |
| Solina | Latin: “of the sun” or “sunny sea” | Suggests warmth and golden ocean light |
| Muriel | Irish: “shining sea” | Old-fashioned but hauntingly beautiful |
| Kailani | Hawaiian: “sea and sky” | Suggests vastness and horizons |
| Talise | Native American (Choctaw): “lovely water” | Gentle, poetic, natural |
Inventing Your Own Mermaid Name
If the names in this guide don’t quite fit your character, you can build one using a few simple patterns.
Pattern 1: Water Word + Feminine Suffix
Take a water-related word and add a suffix that sounds melodic:
- Coral + -ia = Coralia
- Pearl + -ina = Pearlina
- Wave + -ette = Wavette (French-sounding)
- Ocean + -a = Oceana
- Siren + -ella = Sirenella
Pattern 2: Combine Two Languages
Pair a water word from one language with a meaning from another:
- Spanish “mar” (sea) + Greek “ode” (song) = Marode
- Latin “aqua” (water) + French “-belle” (beautiful) = Aquabelle
- Irish “muir” (sea) + Gaelic “-agh” (field) = Muiragh
Pattern 3: Use Literary Sound Patterns
Mermaids in literature often have names with flowing vowels and soft consonants. Notice:
- Multiple a/e sounds: Ariella, Aurelie, Alina
- Double letters: Marella, Sirenna, Cordelia
- Soft endings (-ia, -a, -el, -elle): Neradia, Marita, Siren-el
Sample Dialogue: Naming a Mermaid Character
Writer’s room conversation
You: So the mermaid who helps the hero escape — what should we call her?
Colleague: Something that feels ancient but not too obvious. Not Ariel — that’s taken.
You: What about Ondine? It means “little wave” and it sounds both vulnerable and powerful.
Colleague: Perfect. That also signals to the audience that this isn’t a cute sidekick — it’s a complex character with real depth.
Merman Names (Male Mermaids)
Male mermaids deserve names just as much as females. Here are some options:
| Merman Name | Meaning / Origin | Personality Vibe |
|---|---|---|
| Neptune | Roman god of the sea | Commanding, regal, ancient |
| Triton | Son of Poseidon; messenger god | Diplomatic, articulate, noble |
| Dylan | Welsh: “son of the sea” | Brooding, mysterious, poetic |
| Kai | Hawaiian: “sea” | Adventurous, laid-back, young |
| Oceanus | Titan god of the ocean | Wise, ancient, elemental |
| Nereus | Greek: “old man of the sea” | Ancient, wise, grandfatherly |
| Caspian | Named after the Caspian Sea; also a river name | Independent, geographic, strong |
Example: If you’re writing a rival merman, Triton suggests intelligence and strategy. For a young, reckless merman, Kai works better.
Common Mistakes When Naming Mermaids
✗ Incorrect: Giving your mermaid a name that sounds too modern and landlocked (e.g., “Jennifer” or “Brooklyn”).
✓ Correct: Choosing a name that either has water significance or a lyrical, flowing sound.
Why: Names anchor character identity. A mermaid named Jennifer reads as “landlubber stuck with a mermaid body”, not “creature of the sea.”
✗ Incorrect: Inventing a name that no human can pronounce (e.g., “Zsshyn’theor’la”).
✓ Correct: Creating names that sound alien but remain speakable — your readers need to say it aloud.
Why: Readers will mentally mispronounce hard names and lose immersion. Ariel works because it’s pronounceable; it still feels magical.
✗ Incorrect: Using the same name for every mermaid in your story.
✓ Correct: Varying your mermaid names — mix mythological (Thetis), invented (Coralia), and modern (Marina) for an ensemble cast.
Why: Repetitive patterns make characters blur together. Variety helps readers distinguish them.

Frequently Asked Questions
Is Ariel the only famous mermaid name?
No. Ariel is the most famous in popular culture (thanks to Disney), but historically, Lorelei, Ondine, Amphitrite, and Nerida are equally significant in literature and mythology. Madison (from Splash), Aquamarine, and Syrena represent modern choices.
Can I use a mermaid name for a real child?
Absolutely, if you love it. Marina, Coralia, Ariel, Audine, and Kailani all work as real-world baby names and happen to sound mermaid-like. The difference is intention — are you naming her after mythology/meaning, or are you naming her specifically to sound “magical”? Both are valid.
What makes a name sound “mermaid” vs. just a regular name?
Mermaid names tend to have: flowing vowel sounds (Adriana, Coralia), water-related meanings (Marina, Nerida), lyrical double letters (Aliana, Sirenna), or mythological references. But honestly, any name feels right if your character owns it.
Can I invent a mermaid name from scratch?
Yes. Follow the patterns in the “Inventing Your Own Mermaid Name” section. Combine water words with feminine suffixes, mix languages, or use flowing vowels and soft consonants. Test it by saying it aloud — if it sounds good to your ear, it works.
What’s the difference between a mermaid name and a siren name?
In mythology, sirens are often portrayed as more dangerous and seductive (Lorelei, Sirena), while mermaids are curious or protective (Ariel, Marina). But modern fiction blurs these lines. Choose based on your character’s personality, not strict mythological accuracy.
Should my mermaid have a human name or a mermaid name?
If your mermaid lives in the human world, give her a human name that happens to sound mermaid-like (Marina, Ariel, Coral). If she’s entirely underwater and the human characters only learn her name later, use something more fantastic (Amphitrite, Thalassa, Muirgen). Context matters.
