Nathaniel Bacon of Stiffkey

Sir Nathaniel Bacon (died 7 November 1622), of Stiffkey in Norfolk, was an English lawyer and Member of Parliament (MP).

Nathaniel Bacon was the second son of Sir Nicholas Bacon and half-brother of Sir Francis Bacon. Educated at Trinity College, Cambridge, he was admitted to Gray's Inn in 1562, and became an "ancient" of the Inn in 1576. He was MP for Tavistock (1571–1583), Norfolk (1584–1585, 1593 and 1604–1611, and defeated there in 1601) and King's Lynn (1597–1598); a Puritan, he was an occasionally vocal member of their parliamentary faction during Elizabeth's reign. He also served as High Sheriff of Norfolk in 1586 and 1599, and was knighted in 1604.

Bacon was married twice. He left no male heir; his eldest daughter, Anne, married Sir John Townshend.
