Charles Watkin Williams-Wynn PC was a British politician of the early- to mid-19th century. He held office in both Tory and Whig administrations and was Father of the House of Commons between 1847 and 1850.

Sir Watkin Williams-Wynn, 4th Baronet was a Welsh landowner, politician and patron of the arts. The Williams-Wynn baronets had been begun in 1688 by the politician Sir William Williams, 1st Baronet, but had inherited, in the time of the 3rd baronet, Sir Watkin's father, the estates of the Wynn baronets, and changed their name to reflect this.
