The Roaring Fork Valley is a geographical region in western Colorado in the United States. The Roaring Fork Valley is one of the most affluent regions in Colorado and the U.S. as well as one of the most populous and economically vital areas of the Colorado Western Slope. The Valley is defined by the valley of the Roaring Fork River and its tributaries, including the Crystal and Fryingpan River. It includes the communities of Aspen, Snowmass Village, Basalt, Carbondale, and Glenwood Springs. Mount Sopris and the Roaring Fork River serve as symbols of the Roaring Fork Valley.

State Highway 82 is an 85.3-mile-long (137.3 km) state highway in the U.S. state of Colorado. Its western half provides the principal transportation artery of the Roaring Fork Valley on the Colorado Western Slope, beginning at Interstate 70 (I-70) and U.S. Highway 6 in Glenwood Springs southeast past Carbondale, Basalt and Aspen. From there it continues up the valley to cross the Continental Divide at Independence Pass. On the Eastern Slope, it follows Lake Creek past some of Colorado's highest mountains to Twin Lakes Reservoir, where it ends at US 24 south of Leadville.
