{{TOC limit|2}}

==Location== thumb|Nordenskjöld Coast, Antarctic Peninsula. Larsen Inlet at the northeast end Larsen inlet is at the east end of the Nordenskjöld Coast of the Antarctic Peninsula. It is south of Mount Hornsby and the Detroit Plateau. Mount Tucker and the Longing Peninsula are to the east, and the Sobral Peninsula is to the west. The inlet opens to the south onto the Weddell Sea.{{sfn|Graham Land and South Shetland BAS}} The mouth of the inlet is between Cape Sobral to the west and Cape Longing to the east.

==Discovery and name== Carl Anton Larsen, a Norwegian whaling captain, reported a large bay in this area in 1893, and 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.{{sfn|Alberts|1995|p=419}}

==Glaciology==

The {{convert|350|km2}} Larsen Inlet ice shelf, north of the Larsen A Ice Shelf, was ice-filled in 1986, but mostly ice-free in 1988. The effect of an ice shelf like this disappearing is that glaciers that were held back by it start to side faster into the ocean.{{sfn|Fox|2012}}
