Chicoma Mountain (; also spelled Tschicoma or Tchicoma) is the highest point in the Jemez Mountains, a prominent mountain range in the U.S. State of New Mexico. The tree line in this area is exceptionally high, and the mountain is forested almost all the way to its summit which is conspicuous from the towns of Los Alamos, Santa Fe, and Española and other areas in the valley of the Rio Grande in northern New Mexico. Like the rest of the Jemez, it is of volcanic origin; it lies on the northeast rim of the Valles Caldera, one of the best examples of a caldera in the United States.
