The Régiment de la Chaudière is a Primary Reserve infantry regiment of the Canadian Army. It is part of the 2nd Canadian Division's 35 Canadian Brigade Group and is headquartered at Lévis, Quebec.

The regimental insignia consists of two crossed Vickers machine guns, surmounted by a beaver supporting a fleur-de-lys. Under this is a scroll inscribed with the device Aere perennius meaning 'Stronger than bronze', with a small maple leaf on each end.

Le Régiment de la Chaudière perpetuates three units (1st Battalion, Select Embodied Militia, Dorchester Provincial Light Dragoons and the 1st Lotbinière Division) from the War of 1812 and as such carries Battle Honours which recognize the service of those previous units during the War of 1812 and, in particular, at the Battle of the Chateauguay.

The regiment itself originated in Saint-Anselme, Quebec, on 9 April 1869, as The Provisional Battalion of "Dorchester". It was redesignated as the 92nd "Dorchester" Battalion of Infantry on 12 June 1885. On 1 August 1899, it was amalgamated with the 23rd "Beauce" Battalion of Infantry but retained the same designation.

On 15 December 1936, it amalgamated with the 5th Machine Gun Battalion, CMGC and was redesignated as Le Régiment de la Chaudière (Mitrailleuses).

The regiment mobilized a battalion for the Canadian Active Service Force in 1939. Initially organized as a machine gun battalion, the battalion was sent to England in August 1941. The unit was assigned to the 3rd Canadian Infantry Division as a standard rifle battalion and was designated as a reserve battalion during the D-Day landings in June 1944. Le Régiment de la Chaudière came ashore on the second wave at Bernières-sur-Mer after The Queen's Own Rifles of Canada, surprising the locals who hadn't expected to find francophone troops in the liberating forces. It was the only French-Canadian regiment to participate in Operation Overlord, and one of the few French-speaking units to come ashore that day alongside the bilingual The North Shore (New Brunswick) Regiment and the Free-French Commando Kieffer.

The regiment participated in the Battle for Caen, suffering several casualties in the fight at Carpiquet airfield on 4 July 1944.

With the rest of the division, the regiment fought in the Battle of the Scheldt, notably in actions in the Breskens Pocket between 6 October and 3 November 1944.

The unit wintered in the Nijmegen Salient and was again active in the Rhineland fighting in February 1945, and finished the war on German soil in May.

A 2nd Battalion served in the Reserve Army. A 3rd Battalion was raised for the Canadian Army Occupation Force.
