About Mars city names

A Mars city name works best when it sounds like a place on a map, and the real map of Mars is generous. Its features carry public names: the volcanic rise of Tharsis, the Hellas and Argyre basins, the canyons of Valles Marineris, craters such as Gale and Jezero. This list adds a settlement word to those features instead of repeating them bare, which gives Tharsis Landing, Port Hellas, Jezero Wells, Noctis Terraces and Kasei Locks. The largest Martian valleys are themselves named with the word for Mars in different languages, including Kasei (Japanese), Ma'adim (Hebrew), Mangala (Sanskrit) and Nirgal (Babylonian), so one group leans on those words and on the war god behind the planet's name.

The other groups follow the stages a colony story usually moves through. First come landing and frontier names (Foothold, Touchdown, Second Dawn), then domes, arcologies and lava-tube towns, company camps run by invented mining firms, and New-plus-Earth-city names in many languages. Later eras bring terraforming names of water and green growth, polar camps, free states and hidden cities, and a small share of towns on Phobos and Deimos. Some names honor astronomers who mapped Mars and early science fiction writers.

All 1,000 names are fictional settlements. No city exists on Mars, and nothing here describes a real or planned base.

How to choose Mars city names

  • Pick the region first. A name anchored on a real feature tells readers where the city sits: Pavonis Junction is among the Tharsis volcanoes near the equator, Melas Floor is deep in the canyons, and Korolev Rink belongs to the icy far north.
  • Let the name show the city's age. Foothold, Fourteen Tents and Prefab Row sound like the first hard years, while Lake Jezero and First Rain only make sense after a long terraforming effort.
  • Use the founders' language. A settlement started by crews from Japan, Brazil or Turkey might be Shin-Sapporo, Nova Belém or Yeni Konya rather than one more English New name.
  • Give company towns and free cities different sounds. Ostrander Ice Concession and Lease Block C read as owned property; Free Tharsis and Common Air read as places that govern themselves.
  • On a campaign map or in a city-builder save, mix lengths: keep one or two long formal names for capitals and use short ones such as Ochre, Thaw or Rime for the smaller stops between them.

Frequently asked questions

What are good names for a city on Mars?

For a city tied to the map, try Tharsis Landing, Olympus Gate, Port Hellas or Jezero Wells. For a first settlement, Foothold, Touchdown and Second Dawn carry the frontier mood, and Sevendomes or Lightwell City suit a sealed habitat. Free Tharsis and Elysium Free State fit a colony that has broken away from Earth.

Are these real places on Mars?

The regions, craters and valleys are real feature names, such as Tharsis, Hellas, Jezero and Valles Marineris. Every settlement built on them is fictional. No city exists on Mars, and none of these names refers to a real or planned base.

Which names come from existing science fiction?

A small share nods to older Mars stories. Helium, Zodanga, Ptarth and Gathol are cities in Edgar Rice Burroughs's Barsoom novels, Malacandra is the name of Mars in C. S. Lewis's Out of the Silent Planet, and Aelita is the title of a 1923 novel by Aleksey Tolstoy. Others echo Ray Bradbury story titles or H. G. Wells, such as Million-Year Picnic and Horsell Common, or pair an early writer's surname with a word from one of their titles, such as Weinbaum's Odyssey and Zelazny's Rose. Swap these out if you are publishing your own setting.

Why does the list include towns on Phobos and Deimos?

Stories set on Mars often use its two small moons as ports and waystations, so a small share of the list sits there. Several craters on Phobos are named after characters from Gulliver's Travels, which is where Grildrig, Drunlo and Skyresh come from. Its largest crater, Stickney, is named for Angeline Stickney Hall, whose husband Asaph Hall found both moons in 1877. Seven Hour Moon and Slow Moon play on how quickly Phobos and how slowly Deimos cross the Martian sky.
