In Hawaiian mythology, Nuakea is a beneficent goddess of milk and lactation.
This name was also a title for a wet nurse of royal prince, according to David Malo.
Nuakea was appealed to staunch the flow of milk in the mother's breasts.
Euhemerism
There was a chiefess named after the goddess, Nuakea, wife of Keoloewa, ruling chief of island of Molokai.
Martha Warren Beckwith suggested that this princess was later deified and turned into a goddess.
According to the myth, Nuʻakea was a goddess who came to Earth and married mortal chief Keoloewaakamauaua, but it is known that historical Nuʻakea was born on Oahu island.
