Redbank Creek is born at the confluence of Sandy Lick Creek and the North Fork Creek in the borough of Brookville, then flows west to form the border between Clarion County on the north bank and Armstrong County on the south bank. The tributary Little Sandy Creek joins just upstream of the community of Mayport.
The stream flows 50.3 miles (81 km) to join the Allegheny River and about 64 miles upstream from its confluence, just downstream of the borough of East Brady.
