Baron Ferrers of Groby (or Baron Ferrers de Groby) was a title in the Peerage of England. It was created by writ on 29 December 1299 when William Ferrers, 1st Baron Ferrers of Groby was summoned to parliament. He was the son of Sir William de Ferrers, Knt., of Groby, Leicestershire, (d.1287) by his first wife Anne Durward, 2nd daughter of Alan Durward and his wife Margery of Scotland, and grandson of William de Ferrers, 5th Earl of Derby. The first Baron was married to Ellen de Menteith, daughter of Alexander, Earl of Menteith. In 1475 the eighth baron was created the Marquess of Dorset, and the barony in effect merged with the marquessate. It was forfeited along with the marquessate when the third marquess was attainted in 1554.
