Rock Hill Cotton Factory, also known as Plej's Textile Mill Outlets, Ostrow Textile Mill, and Fewell Cotton Warehouse, is a historic textile mill complex located at Rock Hill, South Carolina. The mill was built in 1881, and is a two-story, 12 bay by 16 bay, brick factory. It features a three-story tower at the main entrance. A number of additions have been made to the building. The Fewell Cotton Warehouse is a one-story, brick and wood frame warehouse built before 1894.

It was listed on the National Register of Historic Places in 1992, with a boundary increase in 2008. The building is now used as a retail and office place known as the Cotton Factory Plaza.
