The El Rey National Park (Spanish: Parque Nacional El Rey) is a national park of Argentina, located in the Anta Department, province of Salta, in the Argentine Northwest, 80 km from the provincial capital.

The park was created in order to preserve a representative sample of the Southern Andean Yungas ecoregion and transition environments.

The fauna includes tapirs, anteaters and peccaries, as well as fish in the rivers, brooks and lakes.

The tapir or anta, which eats aquatic plants, is the largest South American mammal, weighing up to 300 kg.
