Mill Creek is a 6.6-mile-long (10.6 km)[1] tributary of the Schuylkill River in Montgomery County, Pennsylvania, in the United States.
Mill Creek arises from a number of sources east of Lancaster Avenue (U.S. Route 30) from near Villanova south to near Ardmore, and flows east to join the Schuylkill River just upstream from the Gladwyne interchange of the Schuylkill Expressway (Interstate 76 exit 337) and the Flat Rock Dam.
Dove Lake is located beside the northern branch of Mill Creek, just upstream of where Old Gulph Road crosses the creek at a ford. The ford has a gate, which is frequently closed when high water makes crossing it dangerous.
The lower creek has some historic mills and related buildings on Mill Creek Road and nearby Rose Glen Road.
Mill Creek Road follows the south branch of the creek from Montgomery Avenue near Ardmore to River Road by the Schuylkill, mostly on the right bank, but with several crossings near the junction with the north branch.
