How the The Expanse Name Generator works
This Expanse name generator gives names in the style of the books and series: Belters such as Kamal "Kopeng" Pa, Earthers such as Undersecretary Priya Okoye, Martians such as Gunnery Sergeant Ilsa Draper, and ships for your own crew. Pick a faction or mix them.
How the Expanse name generator follows the factions
The Expanse is set in a solar system split three ways, and names show which side you were born on. Belters, raised in low gravity on asteroids and moons, come from every Earth culture mixed together and often go by nicknames in Lang Belta, the creole of the Belt, such as Kopeng, Beratna or Bosmang. Earthers carry the names of a crowded, multicultural Earth, often with a government title. Martians lean towards military ranks and practical names, because the Martian Congressional Republic is built around its navy.
Naming a ship
Ships in The Expanse carry plain, heavy names, often reused or renamed after being salvaged, like the Rocinante, which began life as the Tachi. Martian Navy ships are prefixed MCRN and Earth's UNN. A Belter ice hauler gets a working name; a warship gets something that sounds like it could crush a moon.

FAQ
What are Belter names like?
Belter names mix every Earth culture because the Belt was settled by workers from all over Earth. Many Belters also use a Lang Belta nickname, such as Kopeng for friend or Beratna for brother, alongside their given name.
What does Kopeng mean in Lang Belta?
Kopeng means friend or mate in Lang Belta, the Belter creole built from many Earth languages. Beratna means brother and sésata means sister, and Belters use these words as nicknames and greetings.
Are these characters from the books?
No. The generator invents names in the series' style, and some ship names are reused examples for flavour. Any match with a named character in the books or show is a coincidence.
