Robinson Peak is a 10,793-foot mountain in the northern Sierra Nevada above the west end of Twin Lakes in Mono County, on the boundary of Hoover Wilderness within Humboldt–Toiyabe National Forest. Though moderate by Sierra standards, it stands out for its steep local relief, rising about 3,700 feet above Robinson Creek in just 1.5 miles. Its slopes drain into tributaries of Robinson and Buckeye creeks in the Walker River basin. The peak was named for Robinson Creek, itself named for early pioneer Moses Robinson, who operated a sawmill there in the 1860s. An ascent likely occurred during USGS survey work from 1905 to 1909, with the first documented climb on August 22, 1946.
