Lady Anne Beauchamp, 16th Countess of Warwick (13 July 1426 – 20 September 1492) was the daughter of Richard Beauchamp, 13th Earl of Warwick, and his second wife Isabel le Despenser, a daughter of Thomas le Despenser (22 September 1373 – 13 January 1399/1400) and Constance of York. Anne Beauchamp was the mother of Anne Neville, Queen consort of England as the spouse of King Richard III.
Her older daughter, Lady Isabel, married George, Duke of Clarence, the younger brother of King Edward IV of England. Her younger daughter, Lady Anne Neville, was married to Edward of Westminster, the only son of King Henry VI. When Edward of Westminster was killed in the Battle of Tewkesbury, Anne Neville was married to Richard, Duke of Gloucester, later King Richard III of England. Although their mother was still living, the husbands of the two Neville sisters fought over her inheritance. In order to win his brother George’s final consent to the marriage with Anne, Richard renounced most of Warwick’s land and property including the earldoms of Warwick (which the Kingmaker had held in his wife’s right) and Salisbury and surrendered to Clarence the office of Great Chamberlain of England. After George was executed for treason in 1478, his son Edward inherited the title of Earl of Warwick, while Richard's son was styled Earl of Salisbury.
