Makapuʻu is the extreme eastern end of the Island of Oʻahu in the Hawaiian Islands, comprising the remnant of a ridge that rises 647 feet above the sea. The cliff at Makapuʻu Point forms the eastern tip and is the site of a prominent lighthouse. The place name of this area, meaning "bulging eye" in Hawaiian, is thought to derive from the name of an image said to have been located in a cave here called Keanaokeakuapōloli.
