Elizabeth Stafford, Countess of Sussex

Elizabeth Stafford (c. 1479 – 11 May 1532) was an English noblewoman.

Elizabeth Stafford was the daughter of Henry Stafford, 2nd Duke of Buckingham, and Lady Katherine Woodville, the daughter of Richard Woodville, 1st Earl Rivers, by Jacquetta of Luxembourg, daughter of Pierre de Luxembourg, Count of St. Pol, and was thus a niece of Elizabeth Woodville, queen consort to King Edward IV.

By her father's marriage to Katherine Woodville, Elizabeth Stafford had two brothers, Edward Stafford, 3rd Duke of Buckingham, and Henry Stafford, 1st Earl of Wiltshire, and a sister, Anne, who married firstly, Sir Walter Herbert (died 16 September 1507), an illegitimate son of William Herbert, 1st Earl of Pembroke, and secondly, George Hastings, 1st Earl of Huntingdon.

After the execution of the 2nd Duke of Buckingham, his widow, Katherine Woodville, married Jasper Tudor, second son of Owen Tudor and King Henry V's widow, Catherine of Valois. After Jasper Tudor's death on 21 December 1495, Katherine Woodville married Sir Richard Wingfield (died 22 July 1525). Katherine Woodville died 18 May 1497. After her death, Sir Richard Wingfield married Bridget Wiltshire, daughter and heiress of Sir John Wiltshire of Stone, Kent.
