Greenwood "Green" McCurtain (November 28, 1848 – December 27, 1910) was a tribal administrator and Principal Chief of the Choctaw Republic (1896–1900 and 1902–1906), serving a total of four elected two-year terms. He was the third of his brothers to be elected as chief. (His older brothers Jackson Frazier McCurtain and Edmund McCurtain had previously been elected as chief, serving a total of three terms.) He was a Republican in the late 19th century, leaning toward allotment and assimilation when the nation was under pressure by the United States government, as he believed the Choctaw needed to negotiate to secure their best outcome prior to annexation.
