Fossil Bluff is a seasonal British aircraft refuelling station located on the east coast of Alexander Island in Antarctica.

Fossil Bluff hut sits at the foot of a scree-covered ridge overlooking George VI Sound which separates mountainous Alexander Island from Palmer Land.

To the west and north-west lie Planet Heights, an extensive range of mountains rising to over 1,500 metres (4,900 ft).

The first people to overwinter in 1961 were Cliff Pearce and John Smith (meteorologists) and Brian Taylor (geologist) who carried out a thorough and systematic investigation of the local geology.

Fossil Bluff is a forward-operating facility for refuelling aircraft and is operated by Rothera station during the Antarctic summer season between October and March.
