From the mid-1990's until the 2007-08 school year, the National Association of Intercollegiate Athletics (NAIA) consisted of athletic regions to group certain college athletic conferences and certain independent schools that fit within the geographic footprints. With the formation of the Association of Independent Institutions (A.I.I.; now the Continental Athletic Conference) in fall 2008, the regions would be eventually dissolved.

The West Virginia Intercollegiate Athletic Conference (WVIAC) was a collegiate athletic conference which historically operated exclusively in the state of West Virginia, but briefly had one Kentucky member in its early years, and expanded into Pennsylvania in its final years. It participated in the Division II ranks of the National Collegiate Athletic Association (NCAA), originally affiliated in the National Association of Intercollegiate Athletics (NAIA) until 1995, but held its final athletic competitions in spring 2013, and officially disbanded on September 1 of that year. Its football-playing members announced in June 2012 that they planned to withdraw to form a new Division II conference at the end of the 2012–13 season; this led to a chain of conference moves that saw all but one of the WVIAC's members find new conference homes.
