The state's name is derived from the Choctaw words okla and humma, meaning "red people".<ref name="Oklahoma's Name"/> It is also known informally by its nickname, The Sooner State, in reference to the non-Native settlers who staked their claims on the choicest pieces of land prior to the official opening date, and the Indian Appropriations Act of 1889, which opened the door for white settlement in America's Indian Territory. The name was settled upon statehood, Oklahoma Territory and Indian Territory were merged and Indian was dropped from the name. On November 16, 1907, Oklahoma became the 46th state to enter the union. Its residents are known as Oklahomans, or informally "Okies", and its capital and largest city is Oklahoma City.

With small 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 especially prone to severe weather.<ref name="Oklahoma Terrain"/> In addition to having a prevalence of English, German, Scottish, Scotch-Irish, and Native American ancestry, more than 25 Native American languages are spoken in Oklahoma,<ref name="languages"/> second only to California.

Oklahoma is located 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.
