D River State Recreation Site, State recreation site in Lincoln City, United States

The D River State Recreation Site is a small waterway in Lincoln City that connects Devils Lake to the Pacific Ocean through a sandy beach area. Visitors can stand between freshwater and ocean water, making this spot visually distinct from other coastal locations.

The sources do not record a founding date for the site; it is a state park administered by the Oregon Parks and Recreation Department. Its history is tied to the D River, a 120-foot (37 m) channel linking Devils Lake to the Pacific, which is cited as one of the world's shortest rivers. The park provides public access to Wecoma Beach, part of Lincoln City's 7.5 miles (12.1 km) of oceanfront.

Two of the world's largest kite festivals are held here, one in spring and one in fall, plus a summer festival with professional fliers. Kitelines Magazine named the site one of the best places in the world to fly a kite. Two year-round 10-kilometre Volkssport walking courses also start here.

The site sits on Wecoma Beach in central Lincoln City, with parking and day-use facilities and no fees. Two year-round 10-kilometre Volkssport walking courses start here. Surfing at the river mouth suits intermediate skills, and volunteers help with whale watching for a week in January and a week in March.
