State Highway 13 in the U.S. state of Colorado is a north–south mountain route that travels from Rifle to the Wyoming border near Baggs, Wyoming, through the Rocky Mountains.

The route begins at a diamond interchange with Interstate 70 south of Rifle. It then crosses the Colorado River and intersects U.S. Highway 6 at the south side of Rifle. Along the north side of town the road turns slightly northeastward as it passes through the northern Rifle and into grassland, where it intersects State Highway 325. As the road turns back northward and then slightly northwestward, the surrounding terrain turns into a more barren land dotted with occasional shrubs and grass. As the road continues northwestward, the shrubs and trees become more dense along hillsides. SH 13 then crosses into Rio Blanco County, when the direction becomes straight north. SH 13 then interchanges with State Highway 64, which meets its east end here, and turns abruptly eastward. SH 13 then becomes Market Street as it cuts through the south side of Meeker, paralleling the White River. Following an intersection with a local road leading to Meeker Airport, the road again turns northward back into rural Rio Grande County.
