Baldwin Lake is a small alpine lake located west of Mount Antero (14,269 ft) in the Chalk Creek area of Chaffee County, Colorado, accessible via Forest Road 277 (Baldwin Gulch Road), a rough 4WD route requiring high-clearance vehicles.

The lake is home to native Cutthroat trout and offers dispersed camping opportunities along the road at various elevations, with the most developed camping options available at nearby Iron City, Chalk Lake, and Cascade campgrounds in Chalk Creek Canyon.
