Lac-au-Brochet (French pronunciation: [lak o bʁɔʃɛ]) is an unorganized territory in the Côte-Nord region of Quebec, Canada.

Named after Napoléon-Alexandre Labrie, bishop of the Diocese of Golfe St-Laurent, it was established in the 1950s as a work camp to accommodate Hydro-Québec workers constructing the Bersimis-1 and Bersimis-2 generating stations.

The company town was fully serviced with a hospital, hotel, bank, and shopping plaza.

[4] The community now serves as an access point to the Labrieville ZEC but doesn't have any permanent resident.

It has a surface area of nearly 45 square kilometres (17 sq mi), and is drained by the Brochet River, a tributary of the Betsiamites.
