Mount Discovery ({{coord|78|22|S|165|01|E|name=Mount Discovery}}) is a conspicuous, isolated volcanic cone, {{convert|2680|m}} high, lying at the head of McMurdo Sound and east of Koettlitz Glacier, overlooking the northwest portion of the Ross Ice Shelf.
It forms the center of a three-armed mass of which Brown Peninsula is one extension to the north; Minna Bluff is a second to the east; the third is Mount Morning to the west.
Mount Discovery was discovered by the British National Antarctic Expedition (1901–04) and named for their expedition ship Discovery.{{sfn|Alberts|1995|p=190}}
Location
Mount Discovery lies to the southeast of the lower Koettlitz Glacier. The Brown Peninsula extends to the northeast of the mountain between the Koettlitz Glacier and the Ross Ice Shelf.
Black Island and White Island rise from the ice shelf to the northeast of the mountain.
Minna Bluff, a long peninsula, extends from the southeast of the mountain.
The Eady Ice Piedmont is to the south of the mountain.
A ridge extends southwest from Mount Discovery to Mount Morning.{{sfn|Mount Discovery USGS}}
