Jane Seymour (c. 1508 – 24 October 1537) was Queen of England from 1536 to 1537 as the third wife of King Henry VIII. She died of postnatal complications less than two weeks after the birth of her only child, a son who reigned as King Edward VI.

Jane Seymour was likely born at Wulfhall, Savernake Forest, Wiltshire, the daughter of Sir John Seymour and Margery Wentworth. Through her maternal grandfather, she was a descendant of King Edward III's son Lionel of Antwerp, 1st Duke of Clarence. Because of this, she and King Henry VIII were fifth cousins. She shared a great-grandmother, Elizabeth Cheney, with his second and fifth wives, Anne Boleyn and Catherine Howard.
