Baron Lexinton, Aram (Averham) in the County of Nottingham, was a title in the Peerage of England. It was created on 21 November 1645 for Robert Sutton. The barony became extinct upon the death of his son Robert, the second Baron, in 1723. The family estates passed to Lord Robert Manners-Sutton and subsequently to his brother Lord George Manners-Sutton (see Baron Manners and Viscount Canterbury).
The title is sometime referred to as Baron Lexington.
