The following outline is provided as an overview of and topical guide to the U.S. state of Oklahoma: Oklahoma – state located in the South Central United States. Oklahoma is the 20th most extensive and the 28th most populous of the 50 United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people". 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. A major producer of natural gas, oil, and agricultural products, Oklahoma relies on an economic base of aviation, energy, telecommunications, and biotechnology.
