Sultan Al-Mansur (Jawi: سلطان المنصور;c. 1475 - 1526) was the second Sultan of Tidore in Maluku islands, who reigned from at least 1512 until 1526. Certain legends associate him with the beginnings of Tidore's rule over the Papuan Islands and western New Guinea. During his reign the first visits by Portuguese and Spanish seafarers took place, which led to grave political and economic consequences for the societies of eastern Indonesia. Trying to preserve his realm in the face of Western encroachment, he finally fell victim to Portuguese enmity.
