Amistad National Recreation Area is a national recreation area managed by National Park Service (NPS) that includes the area around the Amistad Reservoir at the confluence of the Rio Grande, the Devils River, and the Pecos River near Del Rio in Val Verde County, Texas. The reservoir was created by the Amistad Dam, completed in 1969, located on the Rio Grande at the United States-Mexico border across from the city of Ciudad Acuña in the Mexican state of Coahuila. Amistad, Spanish for "friendship," refers broadly to the close relationship and shared history between Ciudad Acuña and Del Rio.

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.
