State Route 103 (SR 103) is a 19.97-mile-long (32.14 km) state highway serving the Long Beach Peninsula, located within Pacific County in the U.S. state of Washington. The highway travels north from U.S. Route 101 (US 101) in Seaview through Long Beach and Ocean Park to the southern entrance of Leadbetter Point State Park. SR 103 was created in the 1964 highway renumbering, replacing the earlier Secondary State Highway 12A (SSH 12A) that was created in 1937 to serve Long Beach and Ocean Park, later extended north in 1991 to serve Leadbetter Point State Park.
SR 103 begins as Pacific Way at an intersection with 40th Street, signed as US 101, in Seaview. The highway travels north through the city of Long Beach as Pacific Avenue and enters rural Pacific County on the coast of the Pacific Ocean, passing Briscoe Lake and Loomis Lake. SR 103 travels through Oceanside and Ocean Park, turning east onto Bay Avenue towards Willapa Bay, before continuing north on Sandridge Road through Nahcotta and Oysterville. The highway turns northwest onto Stackpole Road and ends at the southern entrance of Leadbetter Point State Park, west of Stackpole Harbor.
