The Lancaster Cotton Oil Company, established circa 1907 on South Main Street near the Lancaster and Chester Railroad tracks in Lancaster, South Carolina, was an important part of the county’s early twentieth-century industrial development. Founded by John T. Stevens, a prominent businessman from Kershaw, the company processed cottonseed, transforming an agricultural byproduct into valuable commercial materials. Its operations produced cottonseed oil for cooking and other uses, along with cottonseed meal, hulls, and linters for livestock feed, fertilizer, fuel, and manufacturing. The company contributed to the local economy by connecting Lancaster’s cotton-growing region with expanding industrial markets and railroad transportation.

The complex represents an important surviving collection of early industrial buildings and structures associated with South Carolina’s cottonseed-processing industry. Its resources include a cottonseed processing plant, cotton gin, oil storage tanks and shed, office, and a later seed and hull house constructed in 1937. After the original office and seed house burned in 1913, the company continued to expand, and its operations survived the industry’s post-World War I decline into the 1930s and 1940s. Recognized for its architectural and industrial significance, the Lancaster Cotton Oil Company complex was listed in the National Register of Historic Places on February 6, 1990, preserving an important chapter in Lancaster County’s agricultural and commercial heritage.
