Thomas Noel, 2nd Viscount Wentworth

Thomas Noel, 2nd Viscount Wentworth (18 November 1745 – 17 April 1815) was a British politician.

Wentworth was the only son of the Edward Noel, 1st Viscount Wentworth and his wife, Judith, and was educated at Eton and Brasenose College, Oxford. In October 1774, he successfully contested Leicestershire but soon had to leave the Commons when he inherited his father's titles a month later.

On 2 February 1788, he married Mary, Dowager Countess Ligonier, a daughter of the 1st Earl of Northington and widow of the 1st Earl Ligonier of the second creation. The union did not produce any children, although Wentworth had fathered an illegitimate son, Thomas (1774–1853), who became rector of Kirkby Mallory and performed the marriage ceremony of his cousin, Anne Isabella to Lord Byron in 1815.

Upon his death in 1815, 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 her daughter Anne. When Judith died in 1822 and then Lord Curzon died without heirs in 1856, the abeyancy was terminated in favour of Anne.
