In Hawaiian mythology, Kaulu is a trickster god who killed goddess Haumea at Niuhelewai, by catching her in a net obtained from Makalii. He then killed Lonokaeho, also called Piokeanuenue, king of Ko'olau, by singing an incantation.
His parents were Kukaohialaka and Hinauluohia and he was born on Oahu island. His wife was called Kekele and she never bore any children.
