Rajah Siawi (sometimes called Rajah Siagu) was the ruler of the Rajahnate of Kalagan Butuan and Surigao (Surigao) during the arrival of Ferdinand Magellan in Limasawa Island. A cousin of Rajah Humabon of the Rajahnate of Sugbu (Cebu), Rajah Siawi was one of the first rulers (along with Rajah Kulambo, the ruler of Limasawa Island) to accept Christianity and attend the first Catholic Mass in the Philippine Islands.
