George Boleyn, Viscount Rochford (c. 1504 – 17 May 1536) was an English courtier and nobleman who played a prominent role in the politics of the early 1530s, and was the brother of Anne Boleyn, from 1533 the second wife of King Henry VIII and thus the maternal uncle of Queen Elizabeth I (whose reign he did not live to see). Following his father's promotion in the peerage in 1529 to Earl of Wiltshire and Earl of Ormond, he adopted his father's junior title Viscount Rochford (created in 1525) as a courtesy title. He was accused of incest with his sister Anne during the period of her trial for high treason, as a result of which both were executed.
