Sultan Gapi Baguna (Jawi: سلطان ݢاڤي بݢون; c. 1547 – 29 April 1599), also known as Sirajul Arifin (سراج العارفين),[1] was the sixth Sultan of Tidore in Maluku Islands. He reigned from 1560 to 1599, a time of major political realignments. Due to the great expansion of Tidore's rival Ternate, the previous Tidorese hostility towards the Portuguese was changed into a strategic policy of cooperation, while the Spanish establishment in the Philippines and the Iberian Union in 1581 brought him Spanish support.
