Introduction 🌊
Other names for mermaids include merfolk, sirens, merrows, nereids, sea nymphs, undines, and water spirits. Some are true names from folklore, while others are related mythical beings with similar links to water.
People search for another word for mermaid for many reasons. You may need a name for a fantasy character, baby, pet, username, story, game, or creative project. You may also want a word that sounds more mysterious, elegant, ancient, or unusual than simply “mermaid.”
The important thing is that not every water creature is technically a mermaid. A merrow, for example, comes from Irish folklore and is closely linked with merfolk. A nereid is a sea nymph from Greek mythology, while a siren is a different mythical creature that became strongly connected with mermaids in later art and popular culture. Undines are elemental water spirits from European folklore and later occult tradition.
This list brings together real folklore terms, mythical names, and closely related water beings. Each entry explains its meaning, origin, and best use, so you can choose a term that truly fits your idea.

How to Choose the Right Name 🎯
Choosing among other names for mermaids becomes easier when you first decide what kind of name you need.
- Decide if you need a real folklore term. Merrow, nereid, and rusalka have established mythological or folkloric backgrounds.
- Check the exact meaning. A sea nymph, water spirit, and mermaid are not always the same creature.
- Think about your character. A gentle character may suit Pearl or Marina, while a powerful figure may fit Triton or Siren.
- Say the name aloud. This matters if the name will appear often in a story or game.
- Consider the culture. If you choose a name from a living cultural tradition, learn its background instead of using it only because it sounds exotic.
- Separate fact from fantasy. Modern creations such as Aquelle and Seavelle can be fun, but they should not be presented as ancient names.

FAQs 🐚
What is another word for a mermaid?
The broadest modern alternative is merfolk, which can include both mermaids and mermen. Other related terms include merrow, sea nymph, nereid, and siren. However, these words do not all mean exactly the same thing. Some describe separate beings from mythology or folklore.
What is the male version of a mermaid called?
The male version is commonly called a merman. The broader word merfolk can describe a group containing both male and female members. In Greek mythology, Triton is a famous male sea being, although he is a specific mythological figure rather than simply another word for merman.
Is a siren the same as a mermaid?
Not originally. In ancient Greek mythology, sirens were dangerous beings associated with enchanting songs, and they were not described as the familiar fish-tailed mermaids seen today. Later European art and popular culture helped blend the two images, which is why siren is now sometimes used in mermaid-related fiction.
What is a merrow?
A merrow is a type of merfolk from Irish folklore. The word is especially associated with Irish stories about sea-dwelling human-like beings. Merrow is a great choice if you want a character with a clear Irish folklore connection rather than a generic fantasy mermaid.
What is a sea nymph?
A sea nymph is a female nature spirit associated with the sea in mythology. Greek mythology includes several kinds of sea nymphs, including Nereids and Oceanids. They are related to mermaid ideas but are not simply another historical word for mermaid.
What are some good mermaid names for a girl?
Good choices include Marina, Pearl, Coral, Thalassa, Nereid, Thetis, Nerissa, and Calypso. For a traditional mythological feel, Nereid or Thetis works well. For a simple modern name, Marina, Pearl, or Coral may feel more natural.
What is a good rare name for a mermaid character?
Merrow, Thalassa, Undine, Melusine, and Nereid are strong rare choices. Each has a different background, so the best option depends on your story. Merrow gives an Irish folklore feel, while Thalassa has a Greek sea connection and Undine suggests European water-spirit lore.
Conclusion 🌊
There are many ways to name a mermaid, but the best choice depends on the feeling and story behind the name. Merfolk is the broadest modern term, while merrow, nereid, siren, undine, rusalka, and sea nymph point to different traditions and mythical beings.
For a simple name, Pearl, Coral, or Marina can work beautifully. For mythology, Nereid, Thalassa, or Thetis offer deeper roots. If your story needs a darker mood, Rusalka or Melusine may be a better fit.
The most important step is to know what the name really means and where it comes from. A thoughtful choice can make a character feel much more real. Let the sea, the story, and the personality guide your final pick.
