Captain Cook is a census-designated place (CDP) in Hawaiʻi County, Hawaiʻi, in the United States. As of the 2000 census, the CDP population was 3,206. The community, which is actually located in the land division of Kealakekua, is so named because the post office for the area was located in the Captain Cook Coffee Co. during the early 1900s.
Most of Captain Cook lies between the 800- and 2,000-foot (610 m) elevation, which makes it ideal as a coffee growing region. It sits on the top of an ancient fault which created the famous Kealakekua Bay. Prior to the 1960s, most of Captain Cook was part of the vast Kealakekua Ranch, founded in the 1850s by English immigrant Henry Nicholas Greenwell.
