Gilfillan Farm is located at the junction of Washington (U.S. Route 19) and Orr roads in Upper St. Clair Township, Allegheny County, Pennsylvania, United States. It is a working farm whose current form dates to the mid-19th century.

The farm's main house shows the transition from the Greek Revival style to the Victorian modes that became dominant later in the century. It remained a farm in the hands of the same family until 2001, even as the area around it has become a suburb of nearby Pittsburgh. In 1979 it was listed on the National Register of Historic Places, and is currently owned by the township's historical society.
