Sister cities of Trois-Rivières

Trois-Rivières (French pronunciation: ​[tʁwɑ.ʁi.vjɛʁ], local pronunciation: [tʁwɔ.ʁi.vjaɛ̯ʁ]) is a city in the Mauricie region of Quebec, Canada, located at the confluence of the Saint-Maurice and Saint Lawrence Rivers. It is situated in the Mauricie administrative region, on the north shore of the Saint Lawrence River across from the city of Bécancour. It is part of the densely populated Quebec City–Windsor Corridor and is approximately halfway between Montreal and Quebec City. Trois-Rivières is the economic and cultural hub of the Mauricie region. It was founded on July 4, 1634, the second permanent settlement in New France, after Quebec City in 1608.

The city's name, which is French for three rivers, is named for the fact that the Saint-Maurice River, which is divided by two small islands at the river's opening, has three mouths at the Saint Lawrence River. Traditionally, Trois-Rivières was referred to in English as Three Rivers, although in more recent decades it has been referred to as Trois-Rivières in both English and French. The anglicized name still appears in many areas of the town (e.g., the city's Three Rivers Academy), bearing witness to the influence of English settlers in the town. The city's inhabitants are known as "Trifluviens" (Trifluvians).

Trois-Rivières is also the name of a territory equivalent to a regional county municipality (TE) of Quebec, coextensive with the city of Trois-Rivières. Its geographical code is 371. Together with the regional county municipality of Les Chenaux, it forms the census division (CD) of Francheville (37). The municipalities within Les Chenaux and the former municipalities that were amalgamated into Trois-Rivières formerly constituted the regional county municipality of Francheville. Trois-Rivières is the seat of the judicial district of the same name. The Trois-Rivières metropolitan area also includes the city of Bécancour which is situated on the south shore of the St. Lawrence River across the Laviolette Bridge.
