The Jemez River is a tributary of the Rio Grande in eastern Sandoval County, New Mexico, United States.

Both San Antonio Creek and the East Fork Jemez River flow through intricate meanders along their courses.

[4] The Jemez River flows generally south to join the Rio Grande near Bernalillo, north of Albuquerque.

[9] The East Fork Jemez River flows west in a southward curve, through Valle Grande.

The two tributary streams join near Battleship Rock[11] in Cañon de San Diego,[12] forming the Jemez River's main stem.
