Jane Boleyn, Viscountess Rochford (née Jane Parker; c. 1505 – 13 February 1542), was the wife of the Viscount Rochford, brother of Anne Boleyn, the second wife of King Henry VIII. Jane had been a member of the household of Henry's first wife, Catherine of Aragon. It is possible that she played a role in the judgments against, and subsequent executions of, her husband and Anne Boleyn. She was later a lady-in-waiting to Henry's third and fourth wives, and then to his fifth wife, Catherine Howard, with whom she was executed.
