Oklahoma (ə/ (About this soundlisten);[25] Cherokee: ᎣᎦᎳᎰᎹ, ogalahoma;[26] Choctaw: Oklahumma)[27] is a state in the South Central region of the United States,[28] bordered by Kansas on the north, Missouri on the northeast, Arkansas on the east, Texas on the south, New Mexico on the west, and Colorado on the northwest. It is the 20th-most extensive and the 28th-most populous of the fifty United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people".[29] It is also known informally by its nickname, "The Sooner State", in reference to the non-Native settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which dramatically increased European-American settlement in the eastern Indian Territory. Oklahoma Territory and Indian Territory were merged into the State of Oklahoma when it became the 46th state to enter the union on November 16, 1907. Its residents are known as Oklahomans (or colloquially, "Okies"), and its capital and largest city is Oklahoma City.

A major producer of natural gas, oil, and agricultural products, Oklahoma relies on an economic base of aviation, energy, telecommunications, and biotechnology.[30] Both Oklahoma City and Tulsa serve as Oklahoma's primary economic anchors, with nearly two-thirds of Oklahomans living within their metropolitan statistical areas.[31]

With ancient mountain ranges, prairie, mesas, and eastern forests, most of Oklahoma lies in the Great Plains, Cross Timbers, and the U.S. Interior Highlands, a region prone to severe weather.[32] More than 25 Native American languages are spoken in Oklahoma,[33] ranking third behind Alaska and California.

Oklahoma is on a confluence of three major American cultural regions and historically served as a route for cattle drives, a destination for Southern settlers, and a government-sanctioned territory for Native Americans.


The name Oklahoma comes from the Choctaw phrase okla humma, literally meaning red people. Choctaw Nation Chief Allen Wright suggested the name in 1866 during treaty negotiations with the federal government on the use of Indian Territory, in which he envisioned an all-Indian state controlled by the United States Superintendent of Indian Affairs. Equivalent to the English word Indian, okla humma was a phrase in the Choctaw language that described Native American people as a whole. Oklahoma later became the de facto name for Oklahoma Territory, and it was officially approved in 1890, two years after the area was opened to white settlers.[29][34][35]

The name of the state is Pawnee: Uukuhuúwa,[36] and Cayuga: Gahnawiyoˀgeh.[37] In the Chickasaw language, the state is known as Oklahomma', and in Arapaho as bo'oobe' (literally meaning red earth).[38]
