The Hampden Bridge was a heritage-listed wooden Allan Truss bridge over the Murrumbidgee River in Wagga Wagga, Australia. It was officially opened to traffic on 11 November 1895 and named in honour of the NSW Governor Sir Henry Robert Brand, 2nd Viscount Hampden. The bridge carried the Olympic Highway, formerly the Olympic Way, between 1963 until the bridge's closure to highway traffic in October 1995, replaced by the Wiradjuri Bridge. The Hampden Bridge was subsequently converted to local traffic use, then pedestrian use only, and finally demolished in 2014.

A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily because it uses materials efficiently.
