La Prairie (French pronunciation: [la pʁɛʁi]; previously known as Laprairie) is a federal electoral district in Quebec, Canada, that was represented in the House of Commons of Canada from 1867 to 1896, 1968 to 1997 and again since 2015.

The riding of Laprairie was created by the British North America Act of 1867.

In 1987, it was redefined to consist of the towns of Brossard, Candiac, La Prairie et Saint-Lambert.

[2] The Bloc Québécois is more popular in the central and southern portions of the riding, in areas such as Saint-Constant, Sainte-Catherine, Delson and rural areas, with significant support in La Prairie.

The Mohawk reserve of Kahnawake is dominated by the Liberals and NDP, but turnout is generally low.
