Robin of Redesdale (fl. 1469), sometimes called "Robin Mend-All", was the leader of an insurrection against Edward IV of England. His true identity is unknown, but is thought to have been either Sir John Conyers (d. 1469), steward of Middleham, his brother Sir William Conyers of Marske (d. 1475), or both; the two were long-serving retainers of Richard Neville, Earl of Warwick. Graham Evans lists a number of other possibilities such as Sir John Conyers (d. 1490), the father of the previous Sir John and Sir William; Sir Richard Welles (d. 1470), who married Baroness Willoughby de Eresby; her son, Sir Robert Welles (d. 1470), 8th Baron Willoughby de Eresby; or Lord Robert Ogle, Warden of the East March and Lord of Redesdale (d. 1469).
