The Texas Panhandle is a region of Texas consisting of the northernmost 26 counties in the state. The panhandle is a rectangular area bordered by New Mexico to the west and Oklahoma to the north and east. The Handbook of Texas defines the southern border of Swisher County to be the southern boundary of the Texas Panhandle region, though some consider the region to extend as far south as Lubbock County.
