This is a list of defunct college football conferences in the United States. Not all of the conferences listed here are truly defunct. Some simply stopped sponsoring football and continue under their current names, where others changed their names after changes in membership.

Conferences undergoing name changes

Conferences which today exist under the same charter but different names:

  • College Athletic Conference (1962–1991) – Adopted its current name of Southern Collegiate Athletic Conference in 1991, presumably to reflect its traditional geographic focus in the South.
  • Gateway Collegiate Athletic Conference (1985–1992), Gateway Football Conference (1992–2008) – Before 1985, the Gateway Collegiate Athletic Conference was a women's athletic conference whose membership featured several schools now in the Missouri Valley Conference (MVC). When the MVC stopped sponsoring its hybrid Division I-A (now FBS) and Division I-AA (now FCS) football league in 1985, the Gateway Conference took on football as its only men's sport. The initial football membership included the three I-AA football programs then in the MVC. When the women's portion of the Gateway Conference merged with the MVC in 1992, the football conference maintained the Gateway charter, with a name change to Gateway Football Conference. In 2008, the Gateway Conference, by now featuring five current MVC members, changed its name to the Missouri Valley Football Conference to better align itself with the MVC. The two conferences, however, remain legally separate, although they operate out of the same offices in St. Louis.
  • Indiana Collegiate Athletic Conference (1987–1999) – Changed name to the Heartland Collegiate Athletic Conference after it began to admit schools outside Indiana. Still exists as of 2011.
  • Nebraska Intercollegiate Athletic Conference (1969–1992), Nebraska-Iowa Athletic Conference (1992–2000) – Names changed as a result of geographic expansion. Known as the Great Plains Athletic Conference since 2000.
  • Before its most recent expansion, the organization now known as the Pacific-12 Conference officially used three different names and unofficially used two others since the establishment of its current charter in 1959:
    • Athletic Association of Western Universities (AAWU) — Official name from 1959 through June 1968.
    • Big Five — Unofficial name used from 1959 to June 1962, when the conference consisted of charter members California, Stanford, UCLA, USC, and Washington.
    • Big Six — Unofficially adopted when Washington State joined in July 1962, and used through June 1964.
    • Pacific-8 Conference — Unofficially adopted when Oregon and Oregon State joined in July 1964; officially adopted in July 1968.
    • Pacific-10 Conference — Adopted in July 1978 with the arrival of Arizona and Arizona State, and used until Colorado and Utah joined in July 2011.
