The Kīlauea Plantation or Kīlauea Sugar Plantation was a large sugarcane plantation on the north side of Kauaʻi island, Hawaii, including the community of Kīlauea, Hawaii. It was owned and operated by the 1880-incorporated Kīlauea Sugar Company, which became the Kīlauea Sugar Plantation, Co. from 1899 on. The original property was bought by an American, Charles Titcomb, from Kamehameha IV by 1863 who used it for cattle ranching. It was sold to Englishmen John Ross and E.P. Adams, who also leased additional land from Titcomb. Ross and Adams planted sugarcane, then incorporated a firm. It was operated as a plantation from 1880 to 1971.
