The title Baron Mohun was created once in the Peerage of England. On 6 February 1299 John de Mohun was summoned to parliament. On the death of the second baron, the barony fell into abeyance. In 1431, Richard le Strange, 7th Baron Strange (second creation) became sole heir of the barony of Mohun, when both title merged and became abeyant on the death of Ferdinando Stanley, 5th Earl of Derby in 1594.
