The TCU Horned Frogs are the athletic teams that represent Texas Christian University. The 18 varsity teams participate in NCAA Division I and in the Football Bowl Subdivision (FBS) for football, competing mostly in the Big 12 Conference. The school was a founding member of the Southwest Conference and was a member of the Western Athletic Conference, Conference USA (CUSA), and the Mountain West Conference before joining the Big 12. Two TCU teams participate outside the Big 12 in sports not sponsored by that conference. The rifle team competes in the Patriot Rifle Conference, and the beach volleyball team moved to CUSA for 2023–24 after having been in the Coastal Collegiate Sports Association.

College rugby is played by men and women throughout colleges and universities in the United States. Seven-a-side and fifteen-a-side variants of rugby union are most commonly played. Most collegiate rugby programs do not fall under the auspices of the NCAA and are instead governed by National Collegiate Rugby and USA Rugby, two nationwide governing bodies. 27 women's programs participate in the NCAA.
