Landrienne is a township municipality in the Canadian province of Quebec, located in the Abitibi Regional County Municipality. It is part of the census agglomeration of Amos.

Originally known as Saint-Barnabé-de-Landrienne, the place was named in honour of Jean-Marie Landriève Des Bordes (1712–1778), a French naval officer and administrative inspector.

Landrienne was created in 1918 by a contingent of pioneers, who came mainly from Sainte-Thècle and Saint-Prosper, settled along the Transcontinental railroad, in an area 12 km east of the town of Amos and north of La Corne.

In 1926, a large section of Landrienne was taken for the creation of the municipality of Saint-Marc-de-Figuery (along with another section of Figuery-et-Dalquier).

In the 2021 Census of Population conducted by Statistics Canada, Landrienne had a population of 897 living in 398 of its 410 total private dwellings, a change of -7.2% from its 2016 population of 967. With a land area of 275.93 km (106.54 sq mi), it had a population density of 3.3/km (8.4/sq mi) in 2021.
