Sir Watkin Williams-Wynn, 4th Baronet was a British politician and landowner who represented Shropshire and Denbighshire in the House of Commons of Great Britain from 1772 to 1789. 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.
