Seymour may refer to:

Jane Seymour (c. 1508 – 24 October 1537) was Queen of England as the third wife of King Henry VIII. She succeeded Anne Boleyn as queen consort following the latter's execution for trumped up charges of high treason, incest and adultery in May 1536. She died of postnatal complications less than two weeks after the birth of her only child, a son who reigned as Edward VI. She was the only one of Henry's wives to receive a queen's funeral, and his only consort to be buried beside him in St. George's Chapel, Windsor Castle, as she was the only consort to have a male heir.

Jane Seymour was born at Wulfhall, Savernake Forest, Wiltshire, the daughter of Sir John Seymour and Margery Wentworth. Through her maternal grandfather, she was the great-great granddaughter of King Edward III of England through Lionel of Antwerp, 1st Duke of Clarence. Because of this, she and King Henry VIII were fifth cousins. She was a half-second cousin to her predecessor Anne Boleyn, sharing a great-grandmother, Elizabeth Cheney. Her date of birth is a matter of debate. It is usually given as 1509 or even 1510, but it has been noted that at her funeral, 29 women walked in succession. Since it was customary for the attendant company to mark every year of the deceased's life in numbers, this implies she was born in 1508, or 1507 and she had not yet celebrated her 30th birthday.
