Texas Longhorns athletics programs include the extramural and intramural sports teams of the University of Texas at Austin. These teams are referred to as the Texas Longhorns (or variously as Longhorns or 'Horns), taking their name from the Longhorn cattle that were an important part of the development of Texas, and are now the official "large animal" of the US State of Texas. The University of Texas at Austin is the apparent flagship institution of the University of Texas System.
