Robert de Cardeny was a late 14th and early 15th century Scottish cleric. He was the son of one John Cardeny, and brother of the royal mistress Mariota de Cardeny. His early career is obscure. In 1378–80, King Robert II of Scotland petitioned the Pope for a canonry in the diocese of Moray for one Robert de Cardun, despite the fact that the latter already held canonries and prebends in the diocese of Dunblane and Dunkeld. This Robert de Cardun was both a member of King Robert's household and a student at the University of Paris. Robert had graduated from Paris in 1381 as Licentiate. In 1392 he was a receiver of the "English Nation" at Paris and custodian of the Nation's seal. In 1394 Robert was still in Paris, now as Master Robert de Cardeny
