The Colemanville Covered Bridge is a covered bridge that spans Pequea Creek in Lancaster County, Pennsylvania. After Hunsecker's Mill Covered Bridge, it is Lancaster County's second-longest single-span covered bridge still being used. It is also referred to as the Martic Forge Covered Bridge and Pequea #12 Bridge.

The Colemanville Covered Bridge was originally built in 1856 by James C. Carpenter at a cost of $2,244. The bridge has a single-span, wooden, double Burr arch trusses design with the addition of steel hanger rods. The deck is made from oak planks. It is painted red, the traditional color of Lancaster County Covered Bridges, on both the inside and outside. Both approaches to the bridge are painted red with white trim.

After being damaged twice by flooding, it was partially rebuilt in 1938 by Edmund Gardner and in 1973 by David Esh. Lancaster County completely rebuilt the bridge in 1992 for $350,000. During the restoration process, the bridge was raised by 6 feet and moved west a few feet to protect it from damage in potential future flooding.
