Béarn (French pronunciation: [beaʁn] ) is a municipality in northwestern Quebec, Canada, in the Témiscamingue Regional County Municipality.

Settlement of the area began at the end of the 19th century. It was first incorporated as the Parish Municipality of Saint-Placide in 1913, taking its name from the parish that was founded two years earlier.

In 1923, the railroad was built and the place began to be known as Béarn (in honor of the Béarn Regiment). Its post office opened in 1941. Because it was known as Béarn in common use, the name was changed in 1956 to Saint-Placide-de-Béarn, and in 1983, it changed status to municipality and the name was shortened to the current name.

In the 2021 Census of Population conducted by Statistics Canada, Béarn had a population of 708 living in 350 of its 386 total private dwellings, a change of -1.7% from its 2016 population of 720. With a land area of 496.28 km (191.61 sq mi), it had a population density of 1.4/km (3.7/sq mi) in 2021.
