This list of tallest bridges includes bridges with a structural height of at least . The of a bridge is the maximum vertical distance from the uppermost part of a bridge, such as the top of a bridge tower, to the lowermost exposed part of the bridge, where its piers, towers, or mast pylons emerge from the surface of the ground or water. Structural height is different from, which measures the maximum vertical distance between the bridge deck (the road bed of a bridge) and the ground or water surface beneath the bridge span. A separate list of highest bridges ranks bridges by deck height.
The difference between tall and high bridges can be explained in part because some of the highest bridges are built across deep valleys or gorges. For example, (as of 1 July 2020) the Duge Bridge is the highest bridge in the world, but only the fifteenth tallest. This bridge spans a deep river gorge. The bridge's two towers, built on either rim of the gorge, are tall, but due to the depth of the river gorge, the deck height of the Duge Bridge is .
The Millau Viaduct is a cable-stayed bridge that is both tall (in structural height) and high (in deck height). The tallest Millau Viaduct tower is situated near the valley floor, which gives the viaduct a structural height of, and a deck height of above the valley floor. The Millau Viaduct is (as of 9 January 2023) the tallest bridge, but only the thirtieth highest bridge in the world.
