Sultan Megat Iskandar Shah ibni Almarhum Raja Parameswara (died 1424) is believed to be either the first or the second Sultan of Malacca and the son of Parameswara. The position of Megat Iskandar Shah as the second ruler of Malacca has historically been contested. Some argued that he is the same person as Parameswara, but was mistaken as a different person after Parameswara converted to Islam and changed his name, others however disagree that such a mistake could be made, and that Megat Iskandar Shah was indeed the second ruler of Malacca.
