List of rocks on Mars

Martian rocks and outcrops have been studied in-situ by various landers and rovers. While many of the rocks identified on the Martian surface are similar to each other, some have been considered scientifically important or otherwise notable and have been subjected to more extensive study or public interest.

Names for Mars rocks are largely unofficial designations used for ease of discussion purposes, as the International Astronomical Union's official Martian naming system declares that objects smaller than 100 m (330 ft) are not to be given official names.^[1] Because of this, some less significant rocks seen in photos returned by Mars rovers have been named more than once, and others have even had their names changed later due to conflicts or even matters of opinion among researchers. Often rocks are named after the children or family members of astronauts or NASA employees.^{[citation needed]}
