Central Oklahoma is the geographical name for the central region of the U.S. state of Oklahoma. It is also known by the Oklahoma Department of Tourism designation, Frontier Country, defined as the 12-county region including Canadian, Grady, Logan, Oklahoma, Cleveland, McClain, Payne, Lincoln, Pottawatomie, Seminole, Okfuskee, and Hughes counties.

Central Oklahoma is dominated by the largest urban area in the state, the Greater Oklahoma City area. Oklahoma City is the political, economic, tourism, commercial, industrial, financial, and geographical hub of the state, as well as being its primary cultural center. The only Central Oklahoma city which is not officially considered a suburb of Oklahoma City is Stillwater, Oklahoma.

Central Oklahoma is a humid-subtropical region dominated by the Cross Timbers, an area of prairie and patches of forest at the eastern extent of the Great Plains. The region is essentially a transition buffer between the wetter and more forested Eastern Oklahoma and the semi-arid high plains of Western Oklahoma, and experiences extreme swings between dry and wet weather patterns. Climate is dominated by large differences in annual rainfall totals, with Central Oklahoma's western boundary receiving far less rain than compared to its eastern boundary.

Because of these convergences of dry and wet weather patterns, Central Oklahoma is at the heart of what is known as Tornado Alley, and is one of the most tornado-prone areas in the United States.

Central Oklahoma is home to The Oklahoman, the most widely circulated in the state. NewsOK.com is the Oklahoman's online presence. okcBIZ is a monthly publication that covers business news affecting those who live and work in Central Oklahoma.

In 1949, WKY-TV (Channel 4) went on the air and later became the first independently owned television station in the U.S. to broadcast in color. In mid-2002, WKY radio was purchased outright by Citadel Broadcasting; in 2011, Citadel merged with Cumulus Media, who owns and operates WKY to this day. WKY-TV, which is now KFOR-TV, is currently owned by Tribune Broadcasting as of December 2013.
