The Brotonne Bridge (pont de Brotonne) is a bridge in the region of Normandy in France, situated between the cities of Le Havre and Rouen. It has crossed the Seine since 1977, to the east of the commune of Caudebec-en-Caux. Its construction was financed by the General council of Seine-Maritime for the purpose of opening up the Pays de Caux and assuring a connection between the commune of Yvetot and the A13 autoroute by way of the forêt de Brotonne (Brotonne forest), from which the bridge gets its name. Only two bridges are located further downstream the Seine from the pont de Brotonne: the Pont de Tancarville and the Pont de Normandie.

The bridge is a cable-stayed bridge (specifically of the fan design), whose principal span reaches {{convert|320|m|yd}} and is made of prestressed concrete. It is considered an engineering feat and was the first bridge of this type in the world.{{Citation needed|date=October 2020|reason=It is unclear what is the "type" of bridge that makes this the first. The Strömsund Bridge is the first modern cable-stayed bridge. The Pasco-Kennewick Cable Bridge was an earlier prestressed-concrete cable-stayed bridge. So it is unclear which criteria this bridge was 'first' at.)}}

The bridge was a toll bridge until 2006, at which point crossing it became free.

The bridge is considered to be the inspiration for the much larger Sunshine Skyway Bridge in Florida.{{citation needed|date=February 2022}}
