Chicago Peak is a 13,385-foot-elevation (4,080-meter) mountain summit located on the shared boundary of San Miguel County with Ouray County in southwest Colorado, United States. It is situated four miles (6.4 km) east of the community of Telluride, on land managed by Uncompahgre National Forest. It is part of the Sneffels Range which is a subset of the San Juan Mountains, which in turn are part of the Rocky Mountains. It is set above the ghost town of Tomboy, one mile (1.6 km) south of United States Mountain, and one mile northwest of Imogene Pass. Topographic relief is significant as the east aspect rises 2,000 feet (610 meters) above Imogene Basin in approximately one mile, and the west aspect rises 2,000 feet above Savage Basin in less than one mile. Mining activity in the immediate area produced significant amounts of gold and silver.

According to the Köppen climate classification system, Chicago Peak is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers. Due to its altitude, it receives precipitation all year, as snow in winter, and as thunderstorms in summer, with a dry period in late spring. Precipitation runoff from the west side of the mountain drains into tributaries of the San Miguel River, and from the east side into tributaries of the Uncompahgre River.
