The Housatonic River Railroad Bridge is a historic bridge carrying Metro-North Railroad's New Haven Line trackage across the lower Housatonic River in the U.S. state of Connecticut. The bridge is also used by Amtrak for its Northeast Corridor services. It was listed on the National Register of Historic Places in 1987, which also refers to the bridge as the Devon Bridge. It is also referred to as the Devon Railroad Bridge by the state Department of Environmental Protection.

It is a "Scherzer Rolling Lift Bascule"-type bascule bridge.  It has a steel superstructure and block stone piers.  The moveable span is a Warren through truss span. The Connecticut River Railroad Bridge is another bridge of this type in Connecticut which is also NRHP-listed.

The eight bridges from west to east are:  Mianus River Railroad Bridge at Cos Cob, built in 1904; Norwalk River Railroad Bridge at Norwalk, 1896; Saugatuck River Railroad Bridge at Westport, 1905; Pequonnock River Railroad Bridge at Bridgeport, 1902; Housatonic River Railroad Bridge, at Devon, 1906; Connecticut River Railroad Bridge, Old Saybrook-Old Lyme, 1907; Niantic River Bridge, East Lyme-Waterford, 1907; and Thames River Bridge, Groton, built in 1919.
