Zagami is the largest single Martian meteorite ever found, weighing about 18 kilograms (40 lb). It landed 10 feet (3.0 m) from a farmer near Zagami, Nigeria, and became buried in a hole about 2 feet (0.61 m) deep. According to Ron Baalke of NASA/JPL, "The Zagami meteorite is the most easily obtainable SNC meteorite available to collectors," referring to the SNC classification of meteorites (Shergottites, Nakhlites, Chassignites), of which Martian meteorites belong.

Zagamiite is a mineral that was found in the meteorite and is therefore named after it.
