Greaves Peak is a conspicuous sharp, dark, double-pointed rocky peak rising to 240 m in the northwest of Greenwich Island in the South Shetland Islands, Antarctica. The peak surmounts Yakoruda Glacier to the southeast, Archar Peninsula to the west and Razlog Cove to the northwest.
The feature is named after Captain Alexander Benjamin Greaves, Master of the British sealing ship Brussa which visited the South Shetlands in 1821–22.
