Chamizal National Memorial, National memorial park in El Paso, United States.

Chamizal National Memorial is a park in El Paso located at the US-Mexico border, featuring art galleries, a theater, an amphitheater, and a museum focused on border history. The facilities span 54 acres and provide spaces for exhibitions, performances, and cultural programs.

The site marks the 1963 agreement that ended a border dispute lasting more than 100 years between the two nations. Changes in the Rio Grande's path had created confusion about the exact boundary location for generations before a peaceful settlement was reached.

The memorial's cultural center holds art galleries, a theater and an amphitheater, and the museum inside the visitor center traces the history of the U.S.–Mexico border. The Chamizal Convention of 1963 divided the disputed land between the two countries, and a matching Parque Público Federal El Chamizal was created on the Mexican side in Ciudad Juárez.

Park grounds are open 5 a.m. to 10 p.m. daily and close on Thanksgiving, Christmas and New Year's Day. The visitor center and galleries open 10 a.m. to 5 p.m., while the administration office runs 8 a.m. to 4:30 p.m. Groups of 50 or more pay fees for picnic facilities, and the theater requires fees and permits.

The Chamizal Convention of 1963 was negotiated by the International Boundary and Water Commission, created in 1889 to maintain the border and later to divide river waters and manage flood control. The memorial was authorized on June 30, 1966, and became a National Park Service unit on February 4, 1974, the same day it was listed on the National Register of Historic Places.
