Đồng Nai Bridge (Vietnamese: Cầu Đồng Nai) is an important road bridge towards the south of the city of Biên Hòa in Vietnam. It is located along National Highway 1A, and crosses the river, connecting Bình Dương Province to Đồng Nai Province. The bridge has a length of 453.9 metres (1,489 ft), and has 4 lanes, with a curb for pedestrians sides 3.6 metres (12 ft) wide.

The bridge was constructed in 1964, and shows of degradation; more than 44,000 vehicles pass over it per day. Currently, there is another bridge construction project underway in Đồng Nai with two parallel bridges intended to replace this ageing bridge. The new one was built and in use.
