What is the name of the official state holiday celebrated in Hawaii on June 11th?

King Kamehameha I Day on June 11 is a public holiday in the U.S. state of Hawaii. It honors Kamehameha the Great, the monarch who first established the unified Kingdom of Hawaii — comprising the Hawaiian Islands of Niʻihau, Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe, Maui, and Hawaiʻi. In 1883 a statue of King Kamehameha was dedicated in Honolulu by King David Kalākaua (this was a duplicate because the original statue was temporarily lost at sea but was recovered and is now located in North Kohala, Island of Hawaii). There are duplicates of this statue in Emancipation Hall at the Capitol Visitor Center in Washington, D.C. and in Hilo, Island of Hawaii.
