Larsen Inlet () is an ice-filled inlet, 12 nautical miles (22 km) long in a north-south direction and 7 nautical miles (13 km) wide, between Capes Longing and Sobral along the east coast of Graham Land. C.A. Larsen, Norwegian whaling captain, reported a large bay in this area in 1893. Larsen's name was suggested for the feature by Edwin Swift Balch in 1902. The inlet was re-identified and charted by the Falkland Islands Dependencies Survey (FIDS) in 1947.
