In Hawaiian mythology, Laka is the name of two different popular heroes from Polynesian mythology. (In other parts of Polynesia they are known as Rātā, Rata, Lata, Ata, or Lasa). Lengthy legends of their exploits extend throughout the islands, and the kings of Tahiti and Hawaiʻi claimed them as their ancestors.
In one Hawaiian legend, Laka is the son of the Ali’i nui Wahieloa and Hoʻolaukahili, grandson of Kahaʻinuiahema. He plans to sail to Hawaii to avenge the murder of his father, but his canoe-building is thwarted by the little gods of the forest. Because of his offerings to the great gods, however, they give him two outriggers that binds together for his long voyage. He and his companions successfully steal the bones of his father from the cave of Kai-kapu.:263
