Boulder is a town in Garfield County, Utah, United States, 27 miles northeast of Escalante on Utah Scenic Byway 12 at its intersection with the Burr Trail.
As of the 2010 census, the town population was 226, a modest increase over the 2000 figure of 180.


Boulder was quite isolated until the Civilian Conservation Corps built a road from Escalante and did not get electric power until 1947. The town marks the western terminus of Burr Trail, a mostly paved road that runs eastward through spectacular red rock country to the Waterpocket Fold in Grand Staircase-Escalante National Monument. Boulder is the home of Anasazi Indian State Park.
