# Trois-Rivières (federal electoral district)

Trois-Rivières (French:, Canadian French: ; formerly known as Three Rivers and Trois-Rivières Métropolitain) is an electoral district in Quebec, Canada that has been represented in the House of Commons of Canada from 1867 to 1892 and from 1935 to the present.
It was created as "Three Rivers" riding by the British North America Act of 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.
