Sultan Ali Mughayat Syah (died 7 August 1530) was the first sultan of Aceh in northern Sumatra, reigning from about 1514 until his death. Although he was not the first ruler of the Aceh heartland, he is considered the founder of the greater Aceh empire. His time also saw the emergence of the long struggle with the Portuguese for the political and economic supremacy in the Melaka Straits. Sultan Ali's life and career are nevertheless ill-chronicled, and have to be pieced together from various Acehnese, Malay and European accounts.
