The Gagarin Mountains (Russian: Khrebet Yuriya Gagarina; Norwegian: '''Kurzefjella''') are a linear group of mountains, trending in a north–south direction for between the Kurze Mountains and the Conrad Mountains of the Orvin Mountains in Queen Maud Land, East Antarctica.
The Gagarin Mountains were mapped by cartographers of the Norwegian Polar Institute, using aerial photographs and surveys taken by the Sixth Norwegian Antarctic Expedition in 1956–60. They were remapped from surveys and air photos by the Soviet Antarctic Expedition, 1960–61, and named for Soviet cosmonaut Yuri Gagarin.
