Robert Mor Munro, 15th Baron of Foulis (died 1588), and 18th chief of the Clan Munro was a 16th-century Scottish chief. He was known as Robert Mor on account of his large stature. He was the eldest son of Robert Munro, 14th Baron of Foulis. Although this Robert Munro is traditionally 15th Baron and 18th overall chief of the clan, he is only the 8th Munro chief that can be proved by contemporary evidence.
