A Mars-crosser is an asteroid whose orbit crosses that of Mars. The known numbered Mars-crossers are listed here. They include the two numbered Martian Trojans: 5261 Eureka and (26677) 2001 EJ₁₈.

Many databases, for instance the Jet Propulsion Laboratory's online Small-object Database Browser, only list asteroids with a perihelion greater than 1.3 AU as Mars-crossers. An asteroid with a perihelion less than this is classed as a Near Earth Object instead, even though it is crossing the orbit of Mars as well as crossing (or coming near to) that of Earth. Nevertheless, these objects are listed on this page. A grazer is an object with a perihelion below the aphelion of Mars (1.67 AU) but above the Martian perihelion (1.58 AU).^[1]

These objects are not catalogued as Mars-crossers in databases such as the Jet Propulsion Laboratory's online Small-body Database Browser. Instead, they are categorized as Near Earth Objects (NEOs).
