Henry Richard Vassall-Fox, 3rd Baron Holland of Holland, and 3rd Baron Holland of Foxley PC, was an English politician and a major figure in Whig politics in the early 19th century. A grandson of Henry Fox, 1st Baron Holland, and nephew of Charles James Fox, he served as Lord Privy Seal between 1806 and 1807 in the Ministry of All the Talents headed by Lord Grenville and as Chancellor of the Duchy of Lancaster between 1830 and 1834 and again between 1835 and his death in 1840 in the Whig administrations of Lord Grey and Lord Melbourne.

Henry Fox, 1st Baron Holland, PC was an English peer and Whig politician who served as the Secretary at War from 1746 to 1755. He also held the offices of Secretary of State for the Southern Department from 1755 to 1756 and Paymaster of the Forces from 1757 to 1765, enriching himself while holding the latter office. While Fox was widely tipped as a potential candidate for the office of Prime Minister, he never held the office. His third son was the Whig statesman Charles James Fox.
