Tenbridge is a vertical-lift railroad bridge over the Tennessee River in Chattanooga, Tennessee. It has a main span of {{convert|310|ft|m}}.

The original span was a swing span with a center pivot that was originally built in ca. 1879/1880. It was replaced by a vertical lift span in 1917, but the lift towers and machinery were not installed until 1920. It remains a very busy crossing on the Cincinnati, New Orleans and Texas Pacific Railway, a major subsidiary of the Norfolk Southern Railway. The bridge carries two mainline tracks across the river.

The bridge is one of only three known nesting locations in Tennessee for peregrine falcons, a Tennessee endangered species.{{citation needed|date=August 2016}}
