Milford Mills was a village in the Marsh Creek Valley of Chester County, Pennsylvania that was inundated by the construction of the Marsh Creek Dam in 1972.

Milford Mills was one of a cluster of small farming villages in Upper Uwchlan Township settled by Welsh, Scots-Irish and English in the first quarter of the 18th century. Like nearby Lyndell and Dorlan, Milford Mills grew during the 19th century as paper, grain and textile manufacturing flourished. Bypassed by large-scale industry in the late 19th century, the region remained agricultural until after World War II when the Pennsylvania Turnpike brought suburban development.

In 1970-1972, the Marsh Creek Dam was completed and village residents were displaced. The village itself was razed and today, the site lies beneath the 530-acre (2.1 km2) Marsh Creek Lake: part of a drinking water and flood control project operated by the Chester County Water Resources Authority and the State of Pennsylvania.

Abandoned roads and traces of buildings removed for construction of the lake and adjacent recreation areas can still be found throughout Marsh Creek State Park.
