Valyermo (Spanish: "Barren Valley")[1] is an unincorporated community located in the Mojave Desert, in Los Angeles County, California.

Valyermo is located about 17 miles (27 km) southeast of Palmdale in the Antelope Valley portion of Southern California.

Valyermo's location on the edge of the San Bernardino mountains near the desert gives it a cold semi arid climate instead of a cold desert climate with roughly 10 inches of precipitation a year.

"Valyermo" is a contraction of the Spanish words "valle yermo", or "barren valley".

St. Andrew's Abbey is a Roman Catholic monastery (Benedictine) located in the foothills of the Antelope Valley in Valyermo.
