Etar Snowfield (Bulgarian: Ледник Етър \'led-nik 'e-t&r\, Lednik Etar) is a roughly crescent-shaped snowfield draining the west slopes of Oryahovo Heights and the north slopes of Rotch Dome into Barclay Bay between Mercury Bluff and Rowe Point, Livingston Island in the South Shetland Islands, Antarctica. It extends 5 km (3 mi) inland, and 15 km (9 mi) in south-southwest to north-northeast direction. The feature was named after the settlement of Etar in the central Balkan Mountains, Bulgaria.
