Lapulapu (fl. 1521) or Lapu-Lapu, whose name was first recorded as Çilapulapu, was a datu (chief) of Mactan, an island now part of the Philippines. Lapulapu is known for the 1521 Battle of Mactan, where he and his men defeated Spanish forces led by Portuguese explorer Ferdinand Magellan and his native allies Rajah Humabon and Datu Zula. Magellan's death in battle ended his voyage of circumnavigation and delayed the Spanish occupation of the islands by over forty years
