Callahan Creek
Callahan Creek is a stream in Boone County in the U.S. state of Missouri. It is a tributary of Perche Creek.
The stream headwaters arise in northwest Boone County just southeast of Harrisburg adjacent to Missouri Route 124 and it flows south to southeast to its confluence with Perche Creek about one half mile north of I-44 at the northwest corner of Columbia.
A variant name was Callaham's Creek. The creek's name is a corruption of the last name of William Callaham, a pioneer settler.
