Sultan Muda (b. and d. 1579; literally "young sultan") was a nominal sultan of Aceh in northern Sumatra. His brief tenure started a decade-long period of dynastic weakness and strife in the Aceh kingdom. Sultan Muda was the only known child of the previous ruler, Sultan Ali Ri'ayat Syah I. When Sultan Ali died in June 1579, he was nominally succeeded by Sultan Muda who was only four months old. However, the child died after a very short time. He was succeeded by his uncle Sultan Mughal who was the vassal lord of Priaman. The new ruler took the throne name Sultan Sri Alam.
