List of craters on Mars

This is a list of craters on Mars. Impact craters on Mars larger than 1 km exist by the hundreds of thousands, but only about one thousand of them have names. Names are assigned by the International Astronomical Union after petitioning by relevant scientists, and in general, only craters that have a significant research interest are given names. Martian craters are named after famous scientists and science fiction authors, or if less than 60 km in diameter, after towns on Earth. Craters cannot be named for living people, and names for small craters are rarely intended to commemorate a specific town. Latitude and longitude are given as planetographic coordinates with west longitude.

Catalog of named craters
The catalog is divided into three partial lists:
 * List of craters on Mars: A–G
 * List of craters on Mars: H–N
 * List of craters on Mars: O–Z

Names are grouped into tables for each letter of the alphabet, containing the crater's name (linked if article exists), coordinates, diameter in kilometers, year of official name adoption (approval), the eponym ("named after") and a direct reference to the Gazetteer of Planetary Nomenclature.

Statistics
As of 2017, Martian craters account for 21% of all 5,211 named craters in the Solar System. Apart from the Moon, no other body has as many named craters as Mars. Other, non-planetary bodies with numerous named craters include Callisto (141), Ganymede (131), Rhea (128), Vesta (90), Ceres (90), Dione (73), Iapetus (58), Enceladus (53), Tethys (50) and Europa (41).

Largest craters
Some of the largest craters on Mars remain unnamed. Diameters differ depending on source data.
