Lincoln Sea is a body of water in the Arctic Ocean, stretching from Cape Columbia, Canada, in the west to Cape Morris Jesup, Greenland, in the east. The northern limit is defined as the great circle line between those two headlands. It is covered with sea ice throughout the year, the thickest sea ice in the Arctic Ocean, which can be up to 15 m (49 ft) thick. Water depths range from 100 m (330 ft) to 300 m (980 ft). Water and ice from Lincoln Sea empty into Robeson Channel, the northernmost part of Nares Strait, most of the time.

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.

Alert, the northernmost station of Canada, is the only populated place on the shore of Lincoln Sea.

The body of water to the east of Lincoln Sea (east of Cape Morris Jesup) is Wandel Sea.

The International Hydrographic Organization defines the limits of the Lincoln Sea as follows:

On the North. Cape Columbia to Cape Morris Jesup (Greenland).

Abraham Lincoln ⁱ/ˈeɪbrəhæm ˈlɪŋkən/ (February 12, 1809 – April 15, 1865) was the 16th President of the United States, serving from March 1861 until his assassination in April 1865. He successfully led his country through its greatest constitutional, military and moral crisis – the American Civil War – preserving the Union while ending slavery, and promoting economic and financial modernization. Reared in a poor family on the western frontier, Lincoln was mostly self-educated. He became a country lawyer, a Whig Party leader, Illinois state legislator in the 1830s, and a one-term member of the United States House of Representatives in the 1840s. After a series of debates in 1858 that gave national visibility to his opposition to the expansion of slavery, Lincoln lost a Senate race to his arch-rival Stephen A. Douglas. Lincoln, a moderate from a swing state, secured the Republican Party nomination. With almost no support in the South he swept the North and was elected president in 1860. His election was the signal for seven southern slave states to declare their secession from the Union and form the Confederate States of America. The departure of the Southerners gave Lincoln's party firm control of Congress, but no formula for compromise or reconciliation was found. And the war came.
