A map of King George Island

Admiralty Bay (62º10´S 058º25´W) is an irregular bay, 8 km wide at its entrance between Demay Point and Martins Head, indenting the southern coast of King George Island for 16 km in the South Shetland Islands. The name appears on a map of 1822 by Captain George Powell, a British sealer, and is now established in international usage.

The Henryk Arctowski Polish Antarctic Station is situated on the bay.
