The '''Quebec Bridge''' ({{langx|fr|pont de Québec}}) is a road, rail, and pedestrian bridge across the lower [[Saint Lawrence River]] between [[Sainte-Foy, Quebec City|Sainte-Foy]] (a former suburb that in 2002 became the arrondissement [[Sainte-Foy–Sillery–Cap-Rouge]] in [[Quebec City]]) and [[Lévis, Quebec|Lévis]], in [[Quebec, Canada]]. The project failed twice during its construction, in 1907 and 1916, at the cost of 88 lives and additional people injured. The bridge eventually opened in 1919.

The Quebec Bridge is a riveted steel [[Truss bridge|truss structure]] and is {{convert|987|m|ft|abbr=on}} long, {{convert|29|m|ft|abbr=on}} wide, and {{convert|104|m|ft|abbr=on}} high. [[Cantilever bridge|Cantilever arms]] {{convert|177|m|ft|abbr=on}} long support a {{convert|195|m|ft|abbr=on}} central structure, for a total span of {{convert|549|m|ft|abbr=on}}, still the [[List of longest cantilever bridge spans|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 River.

The bridge accommodates [[Quebec Route 175|three highway lanes]] (there were none until 1929, when one was added; another was added in 1949 and a third in 1993), one rail line (two until 1949), and a [[footbridge|pedestrian walkway]] (originally two). At one time, it also carried a streetcar line. Since 1993, it has been owned by the [[Canadian National Railway]].

On 15 May 2024, the Quebec Bridge was purchased by the Federal Government for a symbolic $1.

The Quebec Bridge was designated a [[National Historic Sites of Canada|National Historic Site]] in 1995.
