Lake Roosevelt National Recreation Area is a U.S. national recreation area that encompasses the 130-mile (210 km) long Franklin D. Roosevelt Lake between Grand Coulee Dam and Northport, Washington, in eastern Washington state. The Grand Coulee Dam was built on the Columbia River in 1941 as part of the Columbia River Basin project. Lake Roosevelt National Recreation Area is a unit of the National Park Service and provides opportunities for fishing, swimming, canoeing, boating, hunting, camping, and visiting historic Fort Spokane and St. Paul's Mission. Crescent Bay Lake in Grant County just southwest of Lake Roosevelt also falls under the jurisdiction of the National Recreation Area.

A national recreation area (NRA) is a protected area in the United States established by an Act of Congress to preserve enhanced recreational opportunities in places with significant natural and scenic resources. There are 40 NRAs, which emphasize a variety of activities for visitors, including hiking, camping, boating, fishing, swimming, biking, horseback riding, and wildlife viewing, in areas that include multiple-use management for both conservation and limited utilization of natural resources. They have diverse features and contexts, being established around reservoirs, in urban areas, and within forests. Due to their size, diversity of activities, and proximity to population centers, NRAs are among the most visited units of the National Park System, with six among the thirty most visited sites.
