Pecos National Historical Park is a National Historical Park in New Mexico. It is located about 17 miles east of Santa Fe. The site was originally designated Pecos National Monument on June 28, 1965. In 1990 new lands were added to the park and the official designation was changed to Pecos National Historical Park. It includes the Pecos Pueblo, a National Historic Landmark.

Pecos National Historical Park is composed of several noncontiguous units. The main unit of the park preserves the ruins of Pecos (Ciquique) Pueblo. The first Pecos pueblo was one of two dozen rock-and-mud villages built in the valley around AD 1100 in the prehistoric Pueblo II Era. Within 350 years the Pueblo IV Era Pecos village had grown to house more than 2,000 people in its five-storied complex.
The main unit also protects the remains of Mission Nuestra Señora de los Ángeles de Porciúncula de los Pecos, a Spanish mission near the pueblo built in the early 17th century.
