The Locus 7 Site is an archaeological site in Washington Township, Fayette County, Pennsylvania, United States. Located north of Fayette City, the site lies on a bluff over Downers Run about 2,000 feet (610 m) from the Monongahela River. It is believed to be the location of a former Monongahela village, but its date is uncertain; the village may have existed at any time between 900 and 1600. Its location on a bluff is unusual for Monongahela village sites, but this may have contributed to its preservation; most riverside Monongahela sites in the valley of the Monongahela River have been destroyed by development.
