Colonial Golfers Club is Ohio Northern University's home course located midway between Ada and Lima on Harding Highway.

The layout offers a mix of holes over rolling hills along tree lined fairways with ponds and streams in play, OB along a few of the holes, and sand bunkers primarily guarding the generous, undulating greens. It was designed by Bob Holtsberry in the early 1970s and tips out at 6,886 yards, par 72 72.6/127, course/slope ratings or as short as 4,642 yards from the front tees.
