Buffalo Mill Historic District, Historic textile mill district in Union County, United States.

Buffalo Mill Historic District covers 190 contributing buildings and 2 contributing structures tied to the Buffalo Mill textile complex and its mill village. The main mill carries applied stylized Romanesque Revival detailing, and the complex also holds the mill office, power house, ice factory, warehouse, company store and company bank/drug store. Village housing runs from Queen Anne supervisors' houses to shingle-style bungalows and one-story workers' residences, with a school and a baseball field/park.

The Buffalo Mill textile complex and its mill village were listed on the National Register of Historic Places in 1990 as a district of 190 contributing buildings and 2 contributing structures. The sources record no construction date or architect for the mill; its main building carries applied stylized Romanesque Revival detailing.

The mill village formed a self-contained community where workers lived in company-provided housing and shopped at the company store near their jobs. This setup shows how manufacturers created entire neighborhoods to keep workers close and dependent on the factory.

The grounds spread across a large area with many historic buildings that can be explored on foot, though visitors should allow time to see everything. The best approach is to walk slowly through the village and view each house and building to understand the overall layout.

The area clearly shows the social hierarchy of that time through its buildings: elegant Queen Anne homes for supervisors stand beside simple bungalows for workers. This spatial separation was a deliberate system that reflected the factory's power structure.
