Rock Creek is an urban stream in western Pulaski County, Arkansas. The creek is a tributary of Fourche Creek. Rock Creek passes through the heart of Chenal Country Club, follows Chenal Parkway and Markham Street and passes under the western cloverleaf intersection of I-430 and I-630. The stream then follows the north lane of the Wilbur D. Mills Freeway to Kanis Park, where it turns southeast, south, and then southwest. Rock Creek meanders through Boyle Park before turning southeast again and flowing into Fourche Creek just east of the University Truck Center on South University Avenue.
The graveled Rock Creek Trail follows Rock Creek for one and a half miles from the trailhead at Bowman Curve II on North Bowman Road to its intersection with Loyola Drive.
