One of only 56 limestone streams in the state of Pennsylvania, the creek's headwaters lie in the slate belt, near the borough of Chapman.

From Chapman, the Monocacy follows a 20.3-mile (32.7 km) course through the limestone Lehigh Valley, to its confluence with the Lehigh River in the city of Bethlehem.

Monocacy Creek is not connected to the Monocacy River in Maryland.
