The Lost Creek Bridge is a covered bridge near the unincorporated community of Lake Creek, in Jackson County in the U.S. state of Oregon. The site is about 15 miles (24 km) east-northeast of Medford. At 39 feet (12 m) long, the structure is the shortest covered bridge in Oregon. It carries Lost Creek Road over Lost Creek, a tributary of Little Butte Creek. The bridge was added to the National Register of Historic Places in 1979. In that same year, it was closed to vehicle traffic. A newer concrete bridge runs parallel to the wooden bridge and serves as a bypass.
