Lapu-Lapu (fl. 1521) was a ruler of Mactan in Visayas. Modern Filipino society regards him as the first Filipino hero because he was the first native to resist Spanish colonization. He is best known for the Battle of Mactanthat happened at dawn on April 27, 1521, where he and his soldiers defeated Ferdinand Magellan.

The battle ended up in the killing of Magellan and the end of his expedition and it delayed the Spanish occupation of the islands by over forty years until the expedition of Miguel López de Legazpi in 1564. Monuments to Lapu-Lapu have been built in Manila and Cebu while the Philippine National Policeand the Bureau of Fire Protection use his image.

Besides being a rival of Rajah Humabon of Cebu, little is known about the life of Lapu-Lapu. The only existing documents about his life are those written by Antonio Pigafetta. His name, origins, religion, and fate are still a matter of controversy.

Lapu-Lapu is also known under the names Çilapulapu, Si Lapulapu, Salip Pulaka, Cali Pulaco, and Lapulapu Dimantag.
