Craigsville is an unincorporated community in West Franklin Township Armstrong County, Pennsylvania, United States.

In 1793, William Stephenson and Aaron Wor (from whose name nearby Worthington may have been derived) settled a tract of land just north of the forks of Big and Little Buffalo Creeks.

John Craig was the holder of the tract, and in 1805 his son Samuel established a fulling mill on the banks of Buffalo Creek.

In 1835, partnering with his brother John and a man named Robert Cooper, he began to manufacture flannels, blankets and woolen goods.

14 before the division of Franklin township, is situated on the public road on the lower or right-hand side of the creek, approximately 100 rods below the grist mill.

The village in 1913 had a population of two hundred eighty, most of whom were dependent on the woolen mills for employment, and consisted of thirty-five houses, a school, a church, and two stores.

The major portion of their product went to the blast furnaces in the Pittsburgh district and the remainder generally was used for the manufacture of cement and stone for highway construction.

[2] Graff-Kittanning Clay Products Company was incorporated in 1924, and construction was begun at the Craigsville site in that year.

The products manufactured in both plants was distributed in Maine, New Hampshire, Massachusetts, New York, New Jersey, Delaware, Maryland, and Pennsylvania.

In addition to the oil, one tanker leaked sodium hydroxide that sent a chemical cloud drifting toward Worthington, causing 200 people to be moved from their homes overnight.

Nearly everything has shut down, but the United Methodist Church is still active, and Allegheny Mineral Corporation operates a limestone mine at the site of the old Graff-Kittanning Clay Products Company.
