Lapu-Lapu (floruit-1521) was a ruler of Mactan, an island in the Visayas, Philippines, who is known as the first native of the archipelago to have resisted Spanish colonization. He was also responsible for the death of Portuguese explorer Ferdinand Magellan. He is now regarded, retroactively, as the first Filipino hero. He is also known under the names Çilapulapu, Si Lapulapu, Salip Pulaka, and Khalifa Lapu or Caliph Lapu (alternatively spelled as Cali Pulaco), though the historicity of the names is disputed.
The inhabitants of the Sulu archipelago believe that Lapu-Lapu was a Muslim of the Tausūg people. It is also believed that Lapu-Lapu and Rajah Humabon were the founders of the Sultanate of Cebu.
Lapu-Lapu became one of two datus of Mactan before the Spanish arrived in the archipelago, the other being a certain Zula. When Portuguese explorer and conquistador Ferdinand Magellan arrived in the Philippines in the service of Spain, Zula was one of those who gave tribute to the Spanish king while Lapu-Lapu refused. Others suggest that the Battle of Mactan occurred in Mactang, Camotes Island.
