Caesar Kaluaiku Kamakaʻehukai Kahana Keola Kapaʻakea was a Hawaiian chief who was the patriarch of the House of Kalākaua that ruled the Kingdom of Hawaiʻi from 1874 to 1893. The name Kapaʻakea translates as "the coral or limestone surface" in Hawaiian.

The House of Kalākaua, or Kalākaua Dynasty, also known as the Keawe-a-Heulu line, was the reigning family of the Kingdom of Hawaiʻi under King Kalākaua and Queen Liliʻuokalani. They assumed power after the last king of the House of Kamehameha, Lunalilo, died without designating an heir, leading to the election of Kalākaua and provoking the Honolulu Courthouse riot. The dynasty lost power with the overthrow of Liliʻuokalani and the end of the Kingdom in 1893. Liliʻuokalani died in 1917, leaving only cousins as heirs.
