State Highway 82 (SH 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 (US 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.

At 12,095 feet (3,687 m) above sea level, the traverse of Independence Pass is the highest paved crossing of the Continental Divide in North America, and the highest paved through road on Colorado's state highway network. The pass is closed during the winter months, isolating Aspen from the east and making Highway 82 the only way to reach the popular ski resort town by road. A private foundation has worked with the Colorado Department of Transportation (CDOT), which maintains the road, to undo environmental damage to the alpine tundra created when a disused stagecoach route built across the pass during the Colorado Silver Boom of the 1880s became Highway 82 in the early 20th century.

West of Aspen the highway follows the route of an early Colorado Midland Railroad route from the city to Glenwood Springs. Paved during the 1930s, this road has been gradually expanded to four lanes over the course of the 20th and early 21st centuries. The increased traffic resulting from Aspen's economic rebirth as a resort town has required high-occupancy vehicle lanes, bypasses and the replacement of at least one old bridge. More improvements are planned for both Aspen and Glenwood Springs.
