State Highway 170 (SH 170) is a state highway in Colorado that connects Eldorado Springs and Superior.

The road begins at the edge of Eldorado Canyon State Park at El Dorado Springs. SH 170 then heads eastward, meeting County Road 67 before passing through a rural grassy area. The route then meets State Highway 93, where it becomes Marshall Drive, just north of Marshall Lake. The road then finds its eastern terminus at U.S. Highway 36, the Denver-Boulder Turnpike, passing through the city of Superior.

The entire route is in Boulder County.
