The Valle Nacional River is a river of Oaxaca state in Mexico. The river originates in the Sierra Juárez. The ecology of the region, originally one of pine forests, is threatened by logging, agriculture and grazing.[1] The Valle Nacional flows past San Juan Bautista Valle Nacional, and joins the Santo Domingo River to the southwest of San Juan Bautista Tuxtepec to form the Papaloapan River.
