The Hogback Covered Bridge is a historic covered bridge near Winterset, Madison County, Iowa. Named after a nearby limestone ridge, it was built in 1884 by Harvey P. Jones and George K. Foster over the North River on Douglas Township Road. The 160-foot-long bridge (98-foot truss with 62-foot approaches and 15-foot wide) was designed with a Town lattice truss system overlaid by a Queenpost Frame and built with steel pylons to support the main span. This was the last all-timber truss built in Madison County.

The Hogback Bridge was originally one of 19 covered bridges in Madison County; there are only six remaining covered bridges in the county. In 1992, the bridge was rehabilitated for the cost of $118,810 ($248,000 today). The ridge piers were replaced with steel supports, but the following year in 1993 it was bypassed by a new concrete bridge located only 200 feet south of the bridge.

While most of the covered bridges of Iowa were named after the family who lived the closest to the bridge, the Hogback Bridge is named after a geographical feature. The ridge line at the west end of the valley is formed from two overlapping types of rock that erode at different rates, forming a structure known as a hogback.

The Hogback Covered Bridge was added to the National Register of Historic Places in 1976.
