Mount Foster is a peak rising to 2,025 metres (6,644 ft) in the Imeon Range on Smith Island in the South Shetland Islands of the British Antarctic Territory.

The first ascent was made by Greg Landreth and his team comprising Brice Dowrick, Dan Mannix and Roger Thompson on 29-30 January 1996.

[3][4] The feature is named after Captain Henry Foster, commander of HMS Chanticleer who explored the South Shetlands in 1829.

[5] Traditionally, the elevation of Mount Foster was put at 2,105 metres (6,906 ft).

[6][7][4] However, according to the American high accuracy Reference Elevation Model of Antarctica (REMA) edition 2022, the actual elevation (at 2-meter spatial resolution) is 2,025 m, just 1 m higher than the adjacent Evlogi Peak.
