The Oregon Coast Trail (OCT) is a long-distance hiking route along the Pacific coast of Oregon in the United States. It follows the coast of Oregon from the mouth of the Columbia River to the California border south of Brookings. The trail was envisioned in 1959 by Samuel N. Dicken, a University of Oregon geography professor, approved in 1971 by the Oregon Recreation Trails Advisory Council and developed and managed by the Oregon Parks and Recreation Department as part of the state park system of Oregon.

The Palouse to Cascades State Park Trail gives hikers, cyclists and equestrians a taste of Washington’s scenic diversity from the forested Cascade Mountains to the arid scrublands of eastern Washington. Sitting on the historic Chicago-Milwaukee-St. Paul-Pacific Railroad nicknamed the "Milwaukee Road", the trail runs from Cedar Falls near North Bend (railroad milepost 2136) to the Idaho border (railroad milepost 1850).

Jimmy McCaffrey initially posted the route.  Over time the route evolved, and also there were some differences in exact routes taken by different people.  In late 2020 there was a discussion and agreement among previous FKT holders to determine the exact FKT route.  The route description below, and corrected GPX track, was provided by Chris Thoburn (Chris thanks Jennifer Walker for carefully proofing the new description, as well as to Kristina Randrup and Katy Pieri-McCaffrey for giving it a read for clarity.
