It was created as "Three Rivers" riding by the British North America Act 1867. The electoral district was abolished in 1892 when it was merged into Three Rivers and St. Maurice riding.

The electoral district's English name changed in 1947 to "Trois-Rivières". The riding's name was changed again in 1972 to "Trois-Rivières Métropolitain". Trois-Rivières Métropolitain was abolished in 1976 when it was redistributed into a new "Trois-Rivières" riding and Champlain riding.

This riding lost territory to Saint-Maurice—Champlain and gained territory from Berthier—Maskinongé during the 2012 electoral redistribution.

Geography

The riding, in the Quebec region of Mauricie, consists of most of the city of Trois-Rivières, excepting the former cities of Trois-Rivières-Ouest and Pointe-du-Lac.

The neighbouring ridings are Berthier—Maskinongé, Saint-Maurice—Champlain, and Bas-Richelieu—Nicolet—Bécancour.
