2010–12 Southeastern Conference realignment

The 2010–12 Southeastern Conference realignment refers to the Southeastern Conference (SEC) dealing with several proposed and actual conference expansion and reduction plans among various NCAA conferences and institutions. Moves that involved the SEC were a relatively small part of a much larger NCAA conference realignment that began in the 2010-11 academic year and continued through the first half of 2014. The SEC was one of the least impacted conferences, as no member schools announced plans to join other conferences, while two schools from the Big 12 Conference joined the conference as all-sports members. Several other schools have been rumored as potential expansion candidates.

Although realignment within the NCAA continued into 2013 and 2014, there were no moves or credible rumors involving either current or potential future SEC membership beyond those which took place during 2011-2012.

The SEC last had a membership change in 1992, when Arkansas left the Southwest Conference and South Carolina left the independent ranks to join the conference. This allowed the SEC, which after the additions had 12 members, to split into divisions and hold its first conference championship game in Division I-A football. The SEC had also considered adding Texas, Texas A&M, Florida State, and Miami.

Neither the 1996 nor the 2005 conference realignments affected the SEC, as the conference neither gained nor lost members during either event, although once again Texas and Texas A&M were considered as members in 1996 after the dissolution of the Southwest Conference, before both joining the newly formed Big 12 Conference.
