The Champlain Bridge (French: Pont Champlain) is a steel truss cantilever bridge with approach viaducts constructed of prestressed concrete beams supporting a prestressed concrete deck paved with asphalt. The bridge crosses the Saint Lawrence River, connecting the Island of Montreal to its South Shore suburbs.

Opened in 1962, the structure was degraded by de-icing salt. In 2015, construction began 100 m (330 ft) downstream on a replacement bridge designed to handle higher volumes of traffic. The replacement bridge opened on 1 July 2019, and the old Champlain Bridge was closed to traffic. Demolition will begin in 2019, will take four years, and may cost about $400 million.

Together with the Jacques Cartier Bridge, it was administered by the Jacques Cartier and Champlain Bridges Incorporated (JCCBI), a Canadian Crown Corporation which reports to Infrastructure Canada. Since December 21, 1978, JCCBI was responsible for the management, maintenance and monitoring of the Champlain Bridge.

The bridge saw about 50 million crossings per year, of which 200,000 were buses. On an average weekday, 66% of users were commuters. It was the busiest bridge in Canada upon its closure in 2019.
