Colonel Curtis Piʻehu Iaukea (December 13, 1855 – March 5, 1940) served as a court official, army officer and diplomat of the Kingdom of Hawaii. He later became an influential official for the subsequent regimes of the Provisional Government and the Republic and the Territory of Hawaii.

Iaukea was raised from an early age to serve the Hawaiian royal family. He first gained prominence during the reign of King Kalākaua when he served as an important court official and an army officer in the volunteer army of the Kingdom of Hawaii. He held numerous significant positions including governor of Oahu and chamberlain to the Royal Household. He also served as Hawaii's ambassador to Europe and Asia, attending the coronation of Tsar Alexander III of Russia and the Golden Jubilee of Queen Victoria. Iaukea received numerous Hawaiian honors and foreign decorations during his service to the kingdom. Following the overthrow of the monarchy, he continued to work for the subsequent regimes of the Provisional Government and the Republic of Hawaii. He served as an officer on the military staff of President Sanford B. Dole and represented the Republic at the Diamond Jubilee of Queen Victoria.

After Hawaii's annexation to the United States, he became a member of the Democratic Party of Hawaii and served in many official positions in the newly created Territory of Hawaii including sheriff of Honolulu County, senator of the Third District, secretary of Hawaii, and acting governor of Hawaii. As one of the last surviving representatives of the Hawaiian royal court, he served as business manager and private secretary to the deposed Queen Liliʻuokalani until her death in 1917.
