Alien name tools

Name a whole species from one set of sounds, find out what the sounds in any alien name are and how to say it, and see why astronomers could never use it.

A species kit

The Zessrans
One of them
a Zessra
Homeworld
Seshira
Adjective
Zessran ships, Zessran songs
Names
Ssuarr, Zethath, Zharzak

Say it ZESS-ra. Every name here comes from the same sound set, so the species feels like one people.

What the sounds are

Say it

KRAZ-tix

Sharp: Mostly k, t, z, x and i: the sounds most people match with jagged shapes, like kiki.

Apostrophe: Read it as a glottal stop, the catch in the middle of uh-oh. Klingon and Na'vi write it this way, and Hawaiian writes it with the ʻokina.

Could it name a real planet?

  • 8 characters: the rules allow 4 to 16
  • One word, as the rules prefer
  • No numbers or punctuation, which the rules exclude (an ʻokina is fine where a language uses it)
  • Not invented: the IAU excludes contrived, new names, so every name this generator makes would be turned down

Real names in the search for aliens

  • LGM-1 (1967): Little green men 1, the joke name for the first pulsar, found by Jocelyn Bell Burnell; really PSR B1919+21
  • Wow! (1977): A 72-second radio signal Jerry Ehman circled on a printout; 6EQUJ5 records its strength, not a message
  • SHGb02+14a (2003): A SETI@home candidate signal from Arecibo, never confirmed
  • ʻOumuamua (2017): The first known interstellar object, 1I/2017 U1; Hawaiian for scout, starting with a glottal stop
  • BLC1 (2019): Breakthrough Listen Candidate 1, from the direction of Proxima Centauri; most likely Earth-made interference

How the alien name generator works

Pick an alien type and the generator builds a name from that type's syllable bank: an opening, sometimes a middle syllable, and an ending. Humanoid aliens get balanced names that are easy to say, like Velora or Thalix. Insectoids click with k, t and z sounds, often split by an apostrophe (Kraz'tix). Reptilians hiss with s, sh and zh (Ishkark), aquatic aliens flow with l, m and long vowels (Lirana), and energy beings get bright roots like Lum and Phos, from the Latin and Greek words for light.

Choose how alien a name should be. Easy keeps to sounds any reader can say. Strange borrows the tricks real film languages used: Marc Okrand gave Klingon rare sounds on purpose, such as tlh and a q said deep in the throat, and Na'vi has ejectives written tx, kx and px, while its creator kept it pleasant and sayable for actors. In both, the apostrophe is a glottal stop, the catch in uh-oh.

A filter throws out clumsy letter clusters, everyday English words and common first names, plus the names of famous species and characters from sci-fi shows, films, books and games, so you will not get a Klingon, a Wookiee or a Dalek. Choose Any to mix all five types in one batch.

The names work for a single character, a whole species or the people of a planet. Fiction is full of aliens, though, so search a name before you print it on a book cover or a game box.

That is Quick mode: instant and unlimited. For something more specific, switch to Custom mode, set a few options and add a sentence of details. An AI language model suggests 10 original names, each with how to say it and a suggested meaning, and More like this gives you variations on any name you like.

Tips for choosing a good name

Name the species and the person

Give a species a group name and each character a personal name built from the same sounds. A reptilian called Zharesh might belong to the Zhareshi.

Use apostrophes sparingly

An apostrophe reads as a glottal stop, the catch in uh-oh. One gives a name an alien edge; two or more make it hard to read, so the standard setting never adds more than one.

Match the mouth

Think about how the alien speaks. Mandibles click, forked tongues hiss and gills bubble, so pick the type above that fits the body you imagine.

Read it aloud

Readers and players will sound the name out in their heads. If you stumble over it twice, generate again.

How film aliens got their names

By The Nomezo Editors · Updated October 22, 2026 · How we research names

The best-known alien names come from languages built by linguists. Klingon was designed to sound alien by using sounds that are rare in human languages. For Na'vi, James Cameron asked for a language that sounded alien but pleasant, that the human characters could plausibly learn and that actors could say.

Alien languages built for films
LanguageMade byWhat makes it alien
Klingon (Star Trek, 1984)Marc Okrand, from first words by James DoohanRare sounds on purpose: tlh, a q deep in the throat, and the glottal stop written as an apostrophe
Na'vi (Avatar, 2009)Paul Frommer, a USC linguistEjectives written tx, kx and px, no b, d or g, and a glottal stop in its own name, Na'vi
Kryptonian (Man of Steel, 2013)Christine Schreyer, a UBC Okanagan linguistAbout 300 words, the object before the verb, and a script drawing on Cree syllabics

Other names have homelier roots. Superman's father began as Jor-L before becoming Jor-El of the House of El; Chewbacca comes from sobaka, Russian for dog, after George Lucas's Alaskan Malamute; and Wookiee began as an actor's ad-lib in his film THX 1138.

The apostrophe, decoded

In Klingon and Na'vi the apostrophe is a real sound, a glottal stop: the catch in the middle of uh-oh. Real languages write it too: Hawaiian uses the ʻokina, and Squamish uses the digit 7. Apostrophes in alien names go back further than Star Trek, to J'onn J'onzz, the Martian Manhunter, in 1955; the Vulcans T'Pau and T'Pring followed in 1967, and in Anne McCaffrey's Pern books an apostrophe marks letters dropped from a longer name, so F'lar was once Fallarnon. Readers mind them most when they have no reason.

Sharp or round: bouba and kiki

Shown a jagged shape and a curvy one, about 95% of people call the jagged one kiki and the curvy one bouba, and a 2022 study of speakers of 25 languages found the same pull, if weaker in some. K, t and the vowel i feel spiky; b, m, l, o and u feel round. That is why insectoid and reptilian names here lean on k, t, z and x, and aquatic and energy names on l, m and open vowels.

Real names in the search for aliens

Science names its possible aliens with catalogue codes, not exotic words. The one beautiful exception, ʻOumuamua, the first known visitor from another star, has a Hawaiian name that begins with a glottal stop. Since Enrico Fermi asked where is everybody? in 1950, none of these has been confirmed as a sign of aliens:

Names of signals and objects in the search for alien life
NameYearWhat it is
LGM-11967Little green men 1, the joke name for the first pulsar, found by Jocelyn Bell Burnell; really PSR B1919+21
Wow!1977A 72-second radio signal Jerry Ehman circled on a printout; 6EQUJ5 records its strength, not a message
SHGb02+14a2003A SETI@home candidate signal from Arecibo, never confirmed
ʻOumuamua2017The first known interstellar object, 1I/2017 U1; Hawaiian for scout, starting with a glottal stop
BLC12019Breakthrough Listen Candidate 1, from the direction of Proxima Centauri; most likely Earth-made interference

And if you hoped to name a real planet after your aliens, the International Astronomical Union's rules ask for 4 to 16 characters, one word if possible, nothing offensive, and no contrived, invented names, which rules out every name this generator makes.

How to name an alien

  1. 1

    Start with the body

    Mandibles click, forked tongues hiss and gills bubble: pick the type that fits how the alien speaks.

  2. 2

    Choose how alien

    Easy names suit a main character readers meet often; strange ones, with glottal stops and ejectives, suit something truly other.

  3. 3

    Build the species from one sound set

    A species, its homeworld and its people's names should share sounds, as the Velorans of Velora do.

  4. 4

    Give the apostrophe a reason

    Make it a glottal stop, or dropped letters as in Pern; one per name is plenty.

  5. 5

    Check the famous names

    Search before you print: fiction is full of aliens, and the generator already skips Klingons, Wookiees and Daleks.

Then give them a world: the planet name generator and alien names.

Frequently asked questions

How do you come up with an alien name?

Choose sounds that fit the creature's body and voice: clicking k and t for insects, hissing s and z for reptiles, flowing l and m for sea creatures. Keep it short enough to read easily, or pick an alien type above to do it in one click.

How do you name an alien species?

Many writers take a character or homeworld name and add a group ending such as -i, -an or -ari, so Velora's people become the Veloran. Keep the species name short, because readers will see it often.

What does the apostrophe in alien names mean?

In Klingon and Na'vi it marks a glottal stop, the catch in the middle of uh-oh, and real languages do the same: Hawaiian writes it with the ʻokina. In Anne McCaffrey's Pern books it marks letters dropped from a longer name, so F'lar was once Fallarnon. One apostrophe per name keeps it readable.

What makes an alien name sound scary or friendly?

Sharp sounds such as k, t, z and x, and the vowel i, feel spiky, while b, m, l, o and u feel round. In the bouba/kiki experiments, about 95% of people matched kiki to a jagged shape and bouba to a curvy one, and a 2022 study found the same pull across 25 languages. Spiky names tend to read as menacing, round ones as gentle.

Can I use these alien names in my book or game?

Yes. The names come from original syllable rules and are screened against famous species and characters, so they are free to use in stories, campaigns and games. Search any name before you trademark it.

Could my alien name become a real planet's name?

Not under the current rules. The International Astronomical Union lets the public name some exoplanets, but names must be 4 to 16 characters, without numbers or punctuation, and it excludes contrived, invented names, so every name from this generator would be turned down.

Who invented the Klingon language?

The linguist Marc Okrand, for Star Trek III in 1984, building on a few words James Doohan made up for the first film. He chose sounds that are rare in the world's languages so it would sound alien, and published The Klingon Dictionary in 1985.

Where does the name Chewbacca come from?

From sobaka, the Russian word for dog. George Lucas based the character on his Alaskan Malamute, Indiana, and Wookiee came from an ad-lib in his earlier film THX 1138.

What did scientists call real possible alien signals?

Catalogue codes, mostly. The first pulsar was jokingly nicknamed LGM-1, for little green men, in 1967; the Wow! signal of 1977 is named after the note an astronomer wrote beside it; and BLC1, Breakthrough Listen Candidate 1, was most likely Earth-made interference.

What is Custom mode?

Custom mode lets you set a few options and add a sentence of details. An AI language model then suggests 10 original names, each with how to say it and a suggested meaning, and you can ask for more like any name you like.

Are the meanings in Custom mode real?

For invented names, the meanings are suggestions for your story, not real word origins. AI can make mistakes, so check any claim about a real language before you rely on it.
