Ephraim Bluff is a 425 m ice-free bluff in the south of Breznik Heights, Greenwich Island in the South Shetland Islands, Antarctica. The bluff is linked to Razgrad Peak to the north-northeast and separates the termini of Wulfila Glacier to the northwest and Zheravna Glacier to the east.
The feature was charted and named 'Mount Ephraim' as early as 1820-22 by American sealers who used it as a lead mark for the nearby Yankee Harbour.
