Coatsland is a region in East Antarctica that connects to the west of the Princess Martha Coast belonging to Queen Maud Land and thus forms the eastern coast of the Weddell Sea . It extends in an orientation from southwest to northeast between the 20th and 36th degree west latitude . The northeastern part was discovered by William Speirs Bruce , who led the Scottish National Antarctic Expedition (1902-1904).

The southern (western) part of the area west of 27 ° 54 ′ 0 ″ W is the Prinzregent-Luitpold-Land . The stretch of coast to the east is the Caird Coast .
