Gamma Leporis (γ Lep, γ Leporis) is a star that is located at a distance of about 29 light-years from Earth. Gamma Leporis lies in the south central part of the constellation Lepus, southeast of Beta Leporis and southwest of Delta Leporis. It has a common proper motion companion, AK Leporis, which is a variable star of the BY Draconis type. The star is a member of the Ursa Major Moving Group.
This star is larger than the Sun with 1.2 times the radius of the Sun and 1.3 times the Sun's mass. Based upon its stellar characteristics and distance from Earth, Gamma Leporis was considered a high-priority target for NASA's Terrestrial Planet Finder mission.
