List of craters on Mars

[1] 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 (37 mi) in diameter, after towns on Earth.

Martian craters are listed alphabetically on the following partial lists: 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.

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).

[3] The number of craters on Mars over 25 metres in diameter is suggested to be approximately 90 million.
