The Jemez River is a tributary of the Rio Grande in the U.S. state of New Mexico. The river is formed by the confluence of the East Fork Jemez River and San Antonio Creek, which drain a number of tributaries in the area of the Jemez Mountains and Santa Fe National Forest. The Jemez River is about 50 miles (80 km) long, or about 80 miles (130 km) long if its longest headwater tributary, San Antonio Creek is included. The East Fork Jemez River is about 22 miles (35 km) long. Both San Antonio Creek and the East Fork Jemez River flow through intricate meanders along their courses. It flows generally south to join the Rio Grande near Bernalillo, north of Albuquerque.
