The House of Kamehameha (Hale O Kamehameha), or the Kamehameha dynasty, was the reigning royal family of the Kingdom of Hawaiʻi, beginning with its founding by Kamehameha I in 1795 and ending with the death of Kamehameha V in 1872 and Lunalilo in 1874. The kingdom continued for another 21 years, until its overthrow in 1893 with the fall of the House of Kalakaua.

The Hawaiian Kingdom, also known as Kingdom of Hawaiʻi, was a sovereign state ruled by unelected dynastic families located in the Hawaiian Islands which existed from 1795 to 1893. It was established during the late 18th century when Hawaiian chief Kamehameha I, from the island of Hawaiʻi, conquered the islands of Oʻahu, Maui, Molokaʻi, and Lānaʻi, and unified them under one government. In 1810, the Hawaiian Islands were fully unified when the islands of Kauaʻi and Niʻihau voluntarily joined the Hawaiian Kingdom. Two major dynastic families ruled the kingdom, the House of Kamehameha and the House of Kalākaua.
