Thomas Noel, 2nd Viscount Wentworth (18 November 1745 – 17 April 1815) was a British politician who succeeded to a peerage before he could take his seat in the House of Commons, having just been elected in 1774.
Upon his death in 1815 aged 69, Lord Wentworth's viscountcy became extinct, whilst the barony of Wentworth became abeyant between his nephew Hon. Nathaniel Curzon (later Lord Curzon) and his sister, Judith (and after her, her daughter Anne Isabella Byron, Baroness Byron). When Judith died in 1822 and then Lord Curzon died without heirs in 1856, the abeyance was terminated in favour of Anne.
