The Hot Metal Bridge is a truss bridge in Pittsburgh, Pennsylvania, that crosses the Monongahela River. The bridge consists of two parallel spans on a single set of piers: the former Monongahela Connecting Railroad Bridge, built in 1887, on the upstream side and the former Hot Metal Bridge, built in 1900, on the downstream side. The Monongahela Connecting Railroad Bridge carried conventional railroad traffic, while the Hot Metal Bridge connected parts of the J&L Steel mill, carrying crucibles of molten steel from the blast furnaces to the rolling mills on the opposite bank. The upstream span was converted to road use in 2000, connecting 2nd Avenue near South Oakland with Hot Metal Street (South 29th Street) in the South Side. The downstream span reopened for pedestrian and bicycle use in late 2007 after two years of work.

The Pittsburgh History and Landmarks Foundation is managing a decorative lighting project for the bridge.

The Hot Metal Bridge is the namesake of the Hot Metal Grille at the nearby South Side Works shopping center; the online magazine of the University of Pittsburgh, HotMetalBridge.org; and other local entities.
