Riverside is a municipal golf course on the north side of Janesville on Washington Street along the Rock River.

The layout's fairways are defined by trees along mostly straightforward holes with several interesting doglegs. The course's sand bunkers are one of its main defenses, with various deep and irregularly shaped traps guarding the landing zones and mid-sized, oval greens. Adding interest, a still-in-use railroad runs through a section of the course, with the occasional local freight train passing through. It plays to a par of 72 at 6,508 yards from the tips, 70.7/123, course/slope ratings, and 6,206 yards 69.3/120 from the whites, designed by Robert Bruce Harris.
