Jepson Peak, Mountain peak in San Bernardino Mountains, California, United States.

Jepson Peak is a summit of 3,416 metres in the San Bernardino Mountains, within San Bernardino National Forest and the San Gorgonio Wilderness. It lies 1.9 km west of San Gorgonio Mountain on the same ridge, with Big Draw Peak on that ridge and Charlton Peak to the northwest. Its prominence is under 91 metres, so it is not counted as an independent peak.

The mountain was named after Willis Linn Jepson, a University of California botanist and co-founder of the Sierra Club. This naming honors his work studying and protecting California's mountain environments.

The peak carries the name of Willis Linn Jepson, a University of California botanist and charter member of the Sierra Club; the Sierra Nevada's Mount Jepson honours the same man. Because it rises only about 91 metres above the saddle linking it to San Gorgonio Mountain, many peak lists leave it out, so baggers often reach it as a side trip from the higher summit 1.9 km east.

Jepson Peak lies 1.2 miles (1.9 km) west of San Gorgonio Mountain along the same ridge, so it is usually reached on foot from trails in the San Gorgonio Wilderness. The summit rises to 3,416 m in San Bernardino National Forest, and the South Fork Santa Ana River begins on its north side. Approach from the Mill Creek valley near Forest Falls, about 7 km to the southwest.

Jepson Peak rises 1.2 miles (1.9 km) west of San Gorgonio Mountain, the highest point in Southern California. Its own prominence is under 300 feet (91 m), so most peak lists do not count it as a separate summit, even though it is the second-highest point in the region.
