Baie-Trinité (French pronunciation: [bɛ tʁinite]; Village Municipality) is part of the Manicouagan Regional County Municipality, in Côte-Nord region, Quebec province, Canada.

In addition to Baie-Trinité itself, the village municipality also includes the hamlet of Pointe-des-Monts, site of Pointe-des-Monts Lighthouse.

The Pointe-des-Monts Lighthouse, a National historic site of Canada, was built in 1829–1830 on a point that ancient geographers, since Samuel de Champlain (1567-1655) himself, classified as the demarcation point between the St. Lawrence River and the Gulf of St. Lawrence.

In 2023, all the facilities of the Pointe-des-Monts lighthouse include the lighthouse, the keeper's house and the footbridge. Over time, since its installation in 1830, several buildings have been demolished, as example, given the impressive number of shipwrecks at this time, a provision depot for shipwreck victims was built in 1831.

The first permanent settlers came in 1840, the Baie-de-la-Trinité Mission was established in 1898.

The municipality is located on the north shore of the Gulf of St. Lawrence at the mouth of the Trinity River (French: Rivière de la Trinité), a salmon river which flows through the village.

Mr. Champagne founded the Club 4 H of Baie-Trinité in 1966 and was an important player in the construction of the building that housed the 4-H relay, a rest area for the local population and travellers. The 4-H Clubs of Quebec, which brought together young people aged 8 to 18, were committed to the protection and conservation of the environment. The 4-H movement was created in 1912 in the United States and established in Quebec in 1942 by the Quebec Forestry Association.
