Charles William Wyndham (8 October 1760 – 1 July 1828) was an English politician. He was the third son of Charles Wyndham, 2nd Earl of Egremont and Alicia Maria, daughter of the 2nd Baron Carpenter, and brother of Hon. Percy Charles Wyndham. He was educated at Westminster School from 1767 to 1775, and in 1801 he married Lady Anna Barbara Frances Child Villiers, daughter of the 4th Earl of Jersey and widow of William Henry Lambton of Lambton, County Durham. They had no children. According to some, he "proposed marriage to a gentlewoman one day, married her the next and parted from her the day after" so offspring would have been unlikely.
