William Digges (December 29, 1742 – 1804) was a Virginia planter and politician who represented now-defunct Warwick County, in the Virginia House of Delegates (1778-1784) and during the Virginia Ratification Convention of 1788. Although genealogists disagree as to his father, he was the grandson of Cole Digges who helped found Yorktown. The other two related men of the same name were his uncle and father in law William Digges who represented Warwick County for decades before the Revolutionary War, and great uncle William Digges who represented York County before moving to Maryland and serving in both house of that province's legislature. Because this man married his cousin, and the naming conventions of the day did not restrict "Jr" to a son (but could be used for a younger relative of the same name), this man appears to be the William Digges Jr. who represented York County in the final Virginia Convention alongside his uncle Dudley Digges, and then in the first session of the Virginia House of Delegates where he joined Corbin Griffin, before his Warwick County inheritance.
