The Neville or Nevill family is a noble house of early medieval origin, which was a leading force in English politics in the Late Middle Ages. The family became one of the two major powers in northern England and played a central role in the Wars of the Roses along with their rival, the House of Percy.

The Percy–Neville feud was a series of skirmishes, raids, and vandalism between two prominent northern English families, the House of Percy and the House of Neville, and their followers, that helped provoke the Wars of the Roses. The original reason for the long dispute is unknown, and the first outbreaks of violence were in the 1450s, prior to the Wars of the Roses. The antagonists would later meet in battle several times during the feud.
