La Corne (French pronunciation: [la kɔʁn]) is a municipality in the Canadian province of Quebec in Abitibi Regional County Municipality.

The place is named in honour of Louis de La Corne (1703–1761), a French naval officer who was wounded in the Battle of Sainte-Foy in 1760. Until 1978, the place name was incorrectly spelled as Lacorne.

From 1955 to 1965, La Corne was home to Canada's only lithium mine. The underground mine had a 150 m (490 ft) deep shaft and lateral workings on three levels, and provided lithium to the glass and ceramics industries. With the advent of lithium batteries for electric cars and a myriad of consumer electronic products, the mine is currently being studied for reopening in late 2012 as an open-pit mine.

The municipality of La Corne was founded in 1975 under the name Lacorne. The name was changed to the current La Corne in 1978.
