Broad Creek is a tributary of the lower Susquehanna River located in Harford County, Maryland. Broad Creek originates on the west side of Constitution Road about 500 feet south of the Pennsylvania state line. It runs generally southeast through Pylesville, Maryland for the first half, then northeast for the second half of its 〔U.S. Geological Survey.

It flows through just two properties in its lower five miles, that of the Baltimore Area Council, B.S.A. and then the Exelon power company. In its three mile course through Broad Creek Memorial Scout Reservation, it is dammed to create Lake Aaron Straus and passes close to the Late Archaic Period Broad Creek Soapstone Quarries archaeological site. Downstream from the 1948 Boy Scout dam, the creek forms a noteworthy gorge through the largest and oldest eastern hemlock grove in the state east of the Allegheny Front.〔U.S. Department of Agriculture U.S. National Forest Service.

The watershed is , all in Harford County except for three small areas in York County, Pennsylvania about two miles east of Fawn Grove, 1.5 miles northwest of Whiteford, Maryland, and the southeast part of Delta.
