Creating an alien character for your story or game? I know how hard it is to find the perfect last name that actually sounds believable.
I’ve been there myself. You want a surname that sounds alien but not ridiculous. Something that adds depth to your character and makes readers curious about their backstory.
That’s why I compiled this list of 311 alien last names. I’ve gathered options inspired by distant planets, strange languages, and otherworldly sounds. You’ll find names for every type of sci-fi story, RPG campaign, or fantasy world you’re building.
Let me help you find the perfect fit for your character.
What Makes a Cool Alien Last Name?
What makes an alien last name sound convincing? It starts with the way it sounds when you say it out loud.
Good alien surnames use sharp consonants mixed with flowing vowels. They often include letter combinations we don’t see in English. Think of sounds that feel foreign on your tongue.
Many of the best alien names draw inspiration from space itself. Planets, stars, nebulae, and cosmic events all make great starting points. These references immediately tell readers your character comes from somewhere far beyond Earth.
The strongest alien last names also hint at culture. They suggest whether a species is ancient or newly evolved. Warlike or peaceful. Advanced or primitive.

- Say your name out loud to test pronunciation. It should feel exotic but not impossible to say.
- Keep names between two and four syllables. This length stays memorable without becoming a tongue twister.
- Base sounds on your alien’s home world or culture. Ice planets get sharp sounds while ocean worlds get flowing ones.
