Collins Harbour (62°11′S 58°51′W / 62.183°S 58.850°W / -62.183; -58.850Coordinates: 62°11′S 58°51′W / 62.183°S 58.850°W / -62.183; -58.850) is a bay indenting the south coast of King George Island immediately east of Fildes Peninsula, in the South Shetland Islands. The name appears on a chart by Scottish geologist David Ferguson, who roughly charted the bay in 1913–14, but may reflect an earlier naming.

Bellingshausen Station is located here.
