William Paston, 2nd Earl of Yarmouth (1654 – 25 December 1732) of Oxnead, Norfolk and Turnham Green, Chiswick, Middlesex was a British peer and politician. Born in 1654, he was the son of Robert Paston, 1st Earl of Yarmouth and his wife, Rebecca, née Clayton and was educated at Trinity College, Cambridge. He succeeded his father as 2nd Earl of Yarmouth in 1683, inheriting his estate and Oxnead Hall. He reconverted to Anglicanism in 1689, but refused to swear allegiance to William and Mary when they came to the throne that year, subsequently losing all his offices.
