Kalanikauleleiaiwi was a Chiefess on the island of Hawaii in the late 17th century and early 18th century. She was considered to be the co-ruler of the island of Hawaii with her half-brother, Keaweʻīkekahialiʻiokamoku, the 21st King of Hawaii. Their shared mother was Keakealaniwahine, the ruling Queen of Hawaii. Their son, Keeaumoku Nui, was considered the highest rank of Piʻo and the rightful successor in rank to his father and mother.
Kalanikauleleiaiwi was considered to have higher rank than her half-brother and co-ruler, owing to her paternal descent from the Oahu dynasty of Kākuhihewa. Her father was their mother's half-brother Kāneikaiwilani, who was the son of Iwikauikaua and Kauākahikuaʻanaʻauakāne of Oʻahu. Both her parents shared the father High Chief Iwikauikaua of Oahu (whose symbol was a torch burned at midday, later copied by his descendant Kalākaua).
Her family background has been compared to that of Keōpūolani, with the political power and influence of Kaahumanu. She had four husbands and was the great-grandmother of king Kamehameha I who founded the Kingdom of Hawaiʻi.
