The Martha Pennock House is a set of two historic homes that are located in East Fallowfield Township, Chester County, Pennsylvania.

[1] The older house was built circa 1825 as the Ironmaster's mansion by Martha Pennock, widow of Isaac Pennock, for her son Isaac.

It is a two-story, five-bay, stuccoed, stone, Federal-style dwelling.

The second house was built circa 1840, and is a two-story, four-bay, stuccoed, stone, Greek Revival-style dwelling.

The mill complex where the houses are located was the home of Rebecca Lukens (1794–1854), daughter of Martha Pennock, for a short time after her marriage to Charles Lukens.
