Katherine Woodville (also spelled Catherine Wydville, Wydeville, or Widvile[nb 1]) (c. 1458[1] – 18 May 1497[2]) was the Duchess of Buckingham and a medieval English noblewoman.

When her sister Elizabeth married Edward IV of England, the King elevated and promoted many members of the Woodville family.

A contemporary description of Elizabeth Woodville's coronation relates that Katherine and her husband were carried on squires' shoulders due to their youth.

However, the couple had four children: In 1483, Buckingham first allied himself to the Duke of Gloucester, helping him succeed to the throne as King Richard III, and then to Henry Tudor, leading an unsuccessful rebellion in his name.

[3] After Jasper's death in December 1495, Katherine married – not later than 24 February 1496 – Sir Richard Wingfield, who outlived her.
