Spanish River Boulevard is a short east–west highway in Boca Raton, Palm Beach County, Florida. The eastern is signed as State Road 800 (SR 800), though the western segment was formerly SR 800 as well. The western terminus of the boulevard is at Military Trail (County Road 809 or CR 809), but the state route does not begin until Federal Highway (U.S. Route 1 or US 1). Both the state route and the road itself terminate at Ocean Boulevard (SR A1A) near the Atlantic Ocean shoreline at the northeastern corner of Spanish River Park, near Highland Beach.
