List of Southeastern Conference national championships

The list of Southeastern Conference national championships begins in 1933, the first year of competition for the Southeastern Conference (SEC), and includes 214 team national championships sanctioned by the National Collegiate Athletic Association (NCAA), and four additional national championships sanctioned by the Association for Intercollegiate Athletics for Women (AIAW), won by current conference members through the end of the 2024–25 school year. In 2024–25, SEC members claimed championships in baseball (LSU), men's basketball (Florida), women's gymnastics (Oklahoma), men's swimming & diving (Texas), softball (Texas), women's tennis (Georgia), and women's outdoor track & field (Georgia). So far in 2025–26, the SEC has three national champions: Arkansas in men's indoor track & field, Georgia in women's indoor track & field, and Texas A&M in women's volleyball.

The SEC has averaged almost seven national championships per year since 1990.

Listed below are all championship teams of NCAA-sponsored events, as well as the titles won in football and equestrian, which are not official NCAA-sanctioned championships. Conference members have won at least one title in every sponsored sport in which the SEC participates. Kentucky completed this feat by winning the 2020 National Championship in women's volleyball on April 24, 2021. Between 1979 and 1982, teams representing current member universities also claimed four AIAW Championships.
