Gilbert Hay (b. c. 1403; last mentioned in 1456) or Sir Gilbert the Haye, Scottish poet and translator, was perhaps a kinsman of the house of Errol. If he is the student named in the registers of the University of St Andrews in 1418-1419, his birth may be fixed about 1403. He was in France in 1432, perhaps some years earlier, for a "Gilbert de la Haye" is mentioned as present at Reims, in July 1430, at the coronation of Charles VII. He has left it on record, in the Prologue to his Buke of the Law of Armys, that he was "chaumerlayn umquhyle to the maist worthy King Charles of France." In 1456 he was back in Scotland, in the service of the chancellor, William, , "in his castell of Rosselyn," south of Edinburgh. The date of his death is unknown.
