Mount Pinos, Mountain summit in Los Padres National Forest, California, US.

Mount Pinos is a 8,847-foot (2,697 m) mountain on the Ventura–Kern county line in Los Padres National Forest. Its broad summit plateau holds several subsidiary summits, with open conifer stands separated by chaparral. The mountain consists of granitic rock of the southern Salinian Block, unlike the neighbouring San Emigdio Mountains, and is the highest point in Ventura County.

Mount Pinos is the southernmost point of the Salinian Block, made of granitic rock unlike the neighbouring San Emigdio Mountains, which consist of Precambrian metamorphic or Cenozoic sedimentary rock. The trace of the San Andreas Fault runs northwest of the summit, cutting between Mount Pinos and the mountains immediately to the north and continuing to Soda Lake in the Carrizo Plain along the Elkhorn Scarp. The mountain is sacred to Native Americans in California; John Pryor of California State University, Fresno, notes the land is still used for ceremony.

The Chumash people called this mountain Iwihinmu, and they regarded the summit as the spiritual center of their world. This sacred meaning remains part of local heritage and how the landscape is understood today.

The summit is reached by a 2-mile (3.2 km) hike along a dirt road from a parking area at the end of Los Padres National Forest Road S349S. The trail continues west into the Chumash Wilderness and ends at Cerro Noroeste, with almost all of this 6-mile (9.7 km) route above 8,000 feet (2,400 m). After heavy snowstorms, a snow gate may close Mount Pinos Road lower down, but skiing from the gate is still possible.

The summit plateau is the southernmost point of the Salinian Block, a granitic mass that geologists treat as a separate formation from the neighbouring San Emigdio Mountains, which are made of Precambrian metamorphic or Cenozoic sedimentary rock. The San Andreas Fault trace runs northwest of the peak, cutting between Mount Pinos and the mountains to the north.
