Saint Peters is an historic, nineteenth-century, industrial, company village that is located in Chester County, Pennsylvania, United States.

In 1880, quarrying of the diabase, known locally as "black granite",[6] began, and the "Excursion House" hotel opened, distinguishing the community as both an industrial village and recreational weekend retreat.

Spurs of the Reading Company and Delaware River and Lancaster railroad lines once ran through the village servicing the local mining, forging and quarrying operations.

Local ordinances prevent exterior alterations to historic structures and limit new construction in designated areas in and around the village.

The main street, St. Peter's Road, is lined with private residences, a hotel and restaurant, and number of small specialty shops.
