The Quebec Bridge (Pont de Québec in French) is a road, rail and pedestrian bridge across the lower Saint Lawrence River to the west of Quebec City, and Lévis, Quebec, Canada. The project failed twice, at the cost of 88 lives, and took over 30 years to complete.

The Quebec Bridge is a riveted steel truss structure and is 987 m (3,239 ft) long, 29 m (94 ft) wide, and 104 m (340 ft) high. Cantilever arms 177 m (580 ft) long support a 195 m (640 ft) central structure, for a total span of 549 m (1800 ft), still the longest cantilever bridge span in the world. (It was the all-categories longest span in the world until the Ambassador Bridge was completed in 1929.) It is the easternmost (farthest downstream) complete crossing of the Saint Lawrence.

The Quebec Bridge was designated a National Historic Site of Canada in 1995.
