Moorefield is a town in Hardy County, West Virginia, USA. Moorefield is the county seat of Hardy County. It was originally chartered in 1777 and named for Conrad Moore, who owned the land upon which the town was laid out. The population was 2,544 at the 2010 census. Moorefield is located at the confluence of the South Branch Potomac River and the South Fork South Branch Potomac River.
Moorefield is situated in the South Branch Valley along the South Branch of the Potomac River. Native Americans populated this area for centuries, farming along the river and hunting in the surrounding mountains. English settlers began arriving in the early 18th century, attracted by the fertile land. This early settlement was centered on the community of Old Fields, which is located about five miles to the north of present-day Moorefield. Conflict between the settlers and Native American populations broke out during the French and Indian War. Two fortifications guarded the South Branch Valley in the vicinity of Moorefield.
