Kamehameha II (c. 1797 – July 14, 1824) was the second king of the Kingdom of Hawaii. His birth name was Liholiho and full name was Kalaninui kua Liholiho i ke kapu ʻIolani. It was lengthened to Kalani Kaleiʻaimoku o Kaiwikapu o Laʻamea i Kauikawekiu Ahilapalapa Kealiʻi Kauinamoku o Kahekili Kalaninui i Mamao ʻIolani i Ka Liholiho when he took the throne.
His given name Liholiho was a mononym. Kamehameha is being used as last name in the sense of House of Kamehameha. Hawaiians did not use surnames at the time. His longer formal name was ceremonial. He took the title "King Kamehameha II" upon ascension to co-regent, but preferred to be called ʻIolani, which means "heavenly (or royal) hawk".
