The Blow-Me-Down Covered Bridge is a historic wooden covered bridge carrying Lang Road over Blow-me-down Brook in the town of Cornish, near its northern border with Plainfield, New Hampshire. Built in 1877, the kingpost structure is one of the state's few surviving 19th-century covered bridges. The bridge was listed on the National Register of Historic Places in 1978.

The Blow-Me-Down Covered Bridge is located in a rural section of Cornish, spanning Blow-me-down Brook on Lang Road a short way west of its junction with Platt Road. The bridge structure incorporates a single-span multiple kingpost truss that spans 85 feet (26 m) and has a roadway 14 feet (4.3 m) wide. It rests on natural granite ledges which have been levelled with dry-laid stone. It is covered by a metal roof, with vertical board siding on the sides and around the portals.

The bridge was built in 1877 by James Frederick Tasker (1826–1903) for $528 (equivalent to $15,107 in 2023). The bridge was restored in 1980, and again in 2002. Its single lane is open to vehicular traffic, with a posted weight limit.
