Baron Wharton is a title in the Peerage of England, originally granted by letters patent to the heirs male of the 1st Baron, which was forfeited in 1729 when the last male-line heir was declared an outlaw. The Barony was erroneously revived in 1916 by writ of summons, thanks to an 1844 decision in the House of Lords based on absence of documentation. As such, the current Barony of Wharton could more accurately be listed as a new Barony, created in 1916, with the precedence of the older Barony.

Thomas Wharton, 1st Marquess of Wharton, PC was an English peer and Whig politician. A man of great charm and political ability, he was also notorious for his debauched lifestyle.
