Sir Charles Whitworth (c. 1721 – 21 August 1778)^[1] was a British politician who sat in the House of Commons for 31 years from 1747 to 1778. He was known for his expertise in statistics and finance.

Whitworth was the son of Joan Windham of Clarewell, Gloucestershire, and Francis Whitworth, Member of Parliament for Minehead from 1723 to 1742 and was educated at Westminster School and at Lincoln's Inn. His paternal uncle was Charles Whitworth, 1st Baron Whitworth.^[2]

Whitworth represented the constituencies of Minehead from 1747 until 1761, and Bletchingley until 1768, in which year he was knighted. He then represented Minehead until 1774, East Looe until 1775 and Saltash until his death in 1778. He served in the army for a short time and was made lieutenant-governor of Gravesend and Tilbury for life in 1758. ^[3] Whitworth was Chairman of Ways and Means from 1768 until his death.^[4]
