Baron Killyleagh

Baron Killyleagh is a title in the Peerage of the United Kingdom. It was created on 23 July 1986 by Queen Elizabeth II as a substantive title for her son, the then Prince Andrew (now known as Andrew Mountbatten-Windsor) on the occasion of his marriage to Sarah Ferguson.^[2][3] In November 2025, King Charles III removed Andrew Mountbatten-Windsor's right to be referred to as Prince and to use his titles of nobility. Nonetheless, the title 'Baron Killyleagh' along with Mountbatten-Windsor's superior titles (Duke of York and Earl of Inverness) remain extant in strict legal terms.^[4][5][6]
