约翰逊湾是南极洲的海湾，位于南格鲁吉亚岛西端对开海域的伯德岛西部，处于皮奥角和皮尔逊角之间，现时由南极条约体系管理。

Johnson Cove (54°1′S 38°5′W / 54.017°S 38.083°W / -54.017; -38.083) is a cove entered between Pio Point and Pearson Point on the west side of Bird Island, off the west end of South Georgia. The name appears to be first used in a 1948 British Admiralty pilot (navigation guide).
