Redcliff is a 13,642-foot-elevation (4,158-meter) mountain summit located in Hinsdale County, in southwest Colorado, United States.

Neighbors include Precipice Peak and Dunsinane Mountain along the west-middle Cimarron divide three miles to the north, and nearest higher neighbor Coxcomb Peak one-half mile to the south.

An ascent of Redcliff involves 3,300 feet of elevation gain and 10 miles of hiking, round-trip.

[6] 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 mountain drains into headwaters of both the west and middle forks of the Cimarron River.
