Lincoln Sea is a body of water in the Arctic Ocean. It stretches from Cape Columbia, Canada in the west to Cape Morris Jesup, Greenland in the east.
It is covered with sea ice throughout the year, the thickest sea ice in the Arctic Ocean, which can be up to 15 metres thick.
The depth of the sea ranges from 100 metres to 300 metres.
Water from Robeson Channel, the northernmost part of Nares Strait, empties into this sea.
The sea was named after Robert Todd Lincoln, then United States Secretary of War, on Adolphus W. Greely's 1881-1884 Arctic expedition into Lady Franklin Bay.
