Dunham Bridge is a toll bridge across the River Trent in England. It spans the border between Nottinghamshire and Lincolnshire to the west and east respectively. It forms part of the A57 road, in the section between the Great North Road and Lincoln. It takes its name from the nearby village of Dunham-on-Trent.
The General Estates Company, which also runs the Bathampton and Whitchurch toll bridges, has a stake in the ownership of Dunham Bridge.
