Catherine Parr was Queen of England and Ireland as the last of the six wives of King Henry VIII from their marriage on 12 July 1543 until Henry's death on 28 January 1547. Catherine was the final queen consort of the House of Tudor, and outlived Henry by a year and eight months. With four husbands, she is the most-married English queen. She was the first woman to publish in print an original work under her own name, in English, in England.

In common parlance, the wives of Henry VIII were the six queens consort of King Henry VIII of England between 1509 and his death in 1547. In legal terms, Henry had only three wives, because three of his marriages were annulled by the Church of England. He was never granted an annulment by the Pope, as he desired, however, for Catherine of Aragon, his first wife. Annulments declare that a true marriage never took place, unlike a divorce, in which a married couple end their union. Along with his six wives, Henry took several mistresses.
