In Hawaiian mythology, the Menehune [pronounced meh-neh-HOO-neh] are said to be a people, sometimes described as dwarfs in size, who live in the deep forests and hidden valleys of the Hawaiian Islands, far from the eyes of normal humans. Their favorite food is the maiʻa (banana), but they also like fish.

The Menehune were said to be superb craftspeople. Legends say that the Menehune built temples (heiau), fishponds, roads, canoes, and houses. They are said to have lived in Hawaiʻi before settlers arrived from Polynesia many centuries ago.

In Beckwith's Hawaiian Mythology, there are references to several other forest dwelling races: the Nawao, who were large-sized wild hunters descended from Lua-nuʻu, the mu people, and the wa people.

Some early scholars theorized that there was a first settlement of Hawaiʻi, by settlers from the Marquesas Islands, and a second, from Tahiti. The Tahitian settlers oppressed the "commoners", the manahune in the Tahitian language, who fled to the mountains and were called Menahune. Proponents of this theory point to an 1820 census of Kauaʻi by Kaumualiʻi, the ruling Aliʻi Aimoku of the island, which listed 65 people as menehune.
