Roberts Farm Site is an archaeological site in Manor Township, Pennsylvania, on high ground above the Conestoga River. Long recognized as a Native settlement area, it yielded evidence through excavations in 1931, 1932, and 1971 of a substantial fortified Susquehannock village and cemetery from the Late Woodland and Protohistoric period. The site also shows a much longer span of occupation, from the Late Archaic period until about 1650. Because it preserves this extended record of Indigenous life in the lower Susquehanna region, it holds major historical importance and was placed on the National Register of Historic Places in 1986.
