Sea Lion Glacier (Bulgarian: ледник Морски Лъв, romanized: lednik Morski Lav, IPA: [ˈlɛdnik ˈmɔrski ˈɫɤf]) is the site of an isolated 350 metres (1,150 ft) long glacier on Hurd Peninsula, eastern Livingston Island in the South Shetland Islands, Antarctica. It is located southwest of Hesperides Hill and northwest of Atlantic Club Ridge, separated from the latter by Sea Lion Tarn, and terminating on the South Bay coast.

The glacier, subject of glaciological studies and monitoring for several years since 1993, disappeared completely within a decade.

The midpoint is located at 62°38′46″S 60°22′12″W / 62.64611°S 60.37000°W / -62.64611; -60.37000 (Bulgarian mapping from a 1995–1996 ground survey).
