Nevado Tres Cruces National Park (Spanish pronunciation: [neˈβaðo tɾes ˈkɾuses]) is a national park in the Atacama Region of Chile, east of Copiapó.

The park is divided into two zones, the northern zone encompassing the southern portion of Salar de Maricunga and Laguna Santa Rosa, and the southern area the Laguna del Negro Francisco.

The park is named after Nevado Tres Cruces, which dominates the landscape of the area.

The park is managed by the Corporación Nacional Forestal (National Forest Corporation; CONAF), which offers two refuges in the area: one at the south of Negro Francisco Lagoon and other at the west of Santa Rosa Lagoon.

Located 210 km northeast of Copiapó at 4,126 meters (13,537 feet) above sea level, the lagoon is encircled by the foothills of the Andes.
