The Bear Peninsula extends in a northeast direction from the Walgreen Coast of Marie Byrd Land between the Dotson Ice Shelf to the west and Smith Glacier and the Crosson Ice Shelf to the southeast.

Northern features include, from west to east, Moore Dome, Koloc Point, Park Glacier, Harmon Bay, Gurnon Peninsula, Garwood Point and Hummer Point. Eastern features include, from north to south, Bunner Glacier, Hamilton Ice Piedmont, Merrick Point, Wyatt Hill, Grimes Ridge, Goepfert Bluff, Holt Glacier, Wright Pass, Jones Bluff, Barnes Bluff, Eckman Bluff and Mayo Peak.
Mapping and name
The Bear Peninsula was first delineated from aerial photographs taken by the United States Navy Operation Highjump in January 1947. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) after the ice-ship USS Bear, flagship of the USAS, from which three reconnaissance flights were made in late February 1940, resulting in the discovery of Walgreen Coast (with probable sighting of this feature) and the Thurston Island area. This ship, under the name Bear of Oakland, also served as flagship of the Byrd AE, 1933–35, which based at the Bay of Whales, Ross Ice Shelf. Launched in 1874 at Greenock, Scotland, for use in the sealing trade, she sank in 30-foot seas and high winds in the North Atlantic, March 19, 1963, at which time she was being towed from Nova Scotia to Philadelphia.
