The Vale–West Highway No. 451 is an Oregon state highway in Malheur County. It runs east–west for approximately ten miles (16 km) between two intersections with U.S. Route 20 (US 20) west of Vale and in the city. Highway 451 is also designated as Oregon Route 451 (OR 451).

The OR 451 designation was established in 2003 as part of Oregon's project to assign route numbers to existing named highways that previously were not assigned. As of July 2018, OR 451 is unsigned.
