The Sultanate of Maguindanao (, Filipino: Kasultanan ng Magindanaw Malay: Kesultanan Maguindanao, Jawi: كسولتانن ماڬوايندنااو) was a Maguindanaon Islamic state that ruled parts of the island of Mindanao, in southern Philippines. Its known historical influence stretches from the peninsula of Zamboanga to the bay of Sarangani. At its peak, the sultanate covered the entire island of Mindanao, and ruled over the smaller neighboring islands near and around Mindanao. During the era of European colonization, the Sultanate maintained friendly relations with British and Dutch traders.
