William Luther Kealiʻi Moehonua (1824–1878) was a native Hawaiian noble and politician in the Kingdom of Hawaii.

[5] Lunalilo died after reigning for only one year without naming an heir, so the legislature according to the constitution was to elect a new king.

Moehonua was injured when his carriage was torn apart in the protests that followed, since Queen Emma of Hawaii was favored by the Hawaiian people.

[7] He was replaced as Maui governor by John Owen Dominis, who was married to Lydia Kamakaeha, later Queen Liliʻuokalani.

[8] He probably had at least one child: Kalākaua filed a lawsuit which reached the supreme court in 1883, claiming some land that G. W. Keaweamahi had inherited from Moehonua.

In her autobiography, Liliʻuokalani, who may have been unaware or indifferent, downplays his family background, not mentioning if they were related:He was a most estimable man, far superior to many of a corresponding rank, which was not of the highest; yet he was a good specimen of the Hawaiian race, of noble birth and patriotic sentiments.
