Congress Avenue is a 28.9-mile (46.51 km) long north–south arterial road serving central Palm Beach County, Florida.

Congress Avenue, like the paralleling Military Trail and Jog Road, is a popular commuting alternative to often-congested Interstate 95, Florida's Turnpike, and U.S. Route 1 in Palm Beach County.

Congress Avenue and CR 807 begin at the intersection with Yamato Road (SR 794), near the Boca Raton Tri-Rail station.

In Boynton, the road intersects Gateway Boulevard near the Renaissance Commons, a shopping center and restaurant locale built on the former site of a Motorola plant.

In the neighborhood of Palm Beach Lakes, the road crosses underneath Interstate 95 and proceeds parallel to the east.
