North Texas (also commonly called North Central Texas, Northeastern Texas, and Nortex) is a distinct cultural and geographic area forming the central-northeastern section of the U.S. state of Texas. North Texas is generally considered to include the area south of Oklahoma, east of Abilene, and north of Waco. North Texas, being more precisely the northern part of the central portion of Texas, does not include the Panhandle of Texas, despite the fact that it extends farther north. - Source: Wikipedia
