Sir Thomas Charles Bunbury, 6th Baronet (May 1740 – 14 April 1821) was a British politician who sat in the House of Commons between 1761 and 1812.

[2] While serving as a Whig politician, Bunbury became a strong opponent of the slave trade.

Their notorious marriage, which produced no children - although Sarah gave birth to a daughter fathered by her lover, Lord William Gordon, on 19 December 1768 - was dissolved by Act of Parliament on 14 May 1776, on the grounds of Sarah's adultery.

Bunbury was an important, "crucial" figure in the field of horse racing and Thoroughbred breeding.

[5] He was a steward of the Jockey Club, and his horses included the Epsom Derby winners Diomed, Eleanor, and Smolensko.
