The University Interscholastic League (UIL) was created by The University of Texas at Austin to provide leadership and guidance to public school debate and athletic teachers. Since 1910 the UIL has grown into the largest inter-school organization of its kind in the world. The UIL continues to operate as part of the University of Texas, under the auspices of the Vice President for Diversity & Community Engagement.

The UIL exists to provide educational extracurricular academic, athletic, and music contests. The initials UIL have come to represent quality educational competition administered by school people on an equitable basis.
