Lincoln Rock State Park, State park along Columbia River in Douglas County, United States.

Lincoln Rock State Park is a riverside park along the Columbia River in Douglas County, Washington State. It offers campsites, boat ramps, swimming areas, and picnic facilities spread along the water's edge.

The area took its current shape after the Rocky Reach Dam was built in the late 1950s, which raised the Columbia River level and created the flat shoreline the park sits on today. Washington State then developed the site to give the public access to the new waterfront.

The park is named for a cliff across the water whose profile is compared to Abraham Lincoln; the formation stands opposite the 86-acre site. Turtle Rock Island, a 150-acre nature preserve cut off from the mainland when Lake Entiat formed in the 1960s, can be seen from the park. The land is owned by the Chelan County Public Utility District and managed by Washington State Parks under a lease.

Parking areas for vehicles and boat trailers are clearly marked near the ramps, so arriving with a boat is straightforward. Summer weekends draw large numbers of visitors, so coming early in the day gives you a better chance of finding space.

The park takes its name from a rock formation on the water whose silhouette is said to resemble the profile of Abraham Lincoln. The resemblance is visible from the shore and gives the place its name in a way that surprises many first-time visitors.
