The Francis Farm Petroglyphs are a Native American rock-carving site in southwestern Pennsylvania on a large sandstone boulder in Jefferson Township northwest of Perryopolis. Known since at least 1843, the carvings cannot be assigned with certainty to a single people, though possible makers include the Monongahela or ancestors of the Shawnee during the later Woodland period. James L. Swauger formally documented the site in 1958. At least sixteen surviving carvings include human figures, animals, geometric forms, pits, and abstract shapes, though some nearby marks are modern vandalism. Because many upper Ohio River valley petroglyph sites were destroyed in the twentieth century, this comparatively intact surviving example is an important record of regional Native American rock art.
