Southeast Conference (Wisconsin)
The Southeast Conference is a high school athletic conference consisting of large schools in southeastern Wisconsin. The conference and its member schools are affiliated with the Wisconsin Interscholastic Athletic Association.
History
1993-1997
The Southeast Conference was formed in 1993 as a fifteen-member superconference, taking all of its schools from three recently disbanded conferences. Five members came from the Big Nine, five from the Suburban Park and four from the Braveland. The recently opened Waukesha West High School, which would have become Braveland Conference members but for its dissolution, rounded out the original membership roster of the Southeast Conference. Schools were subdivided by geography along previous conference alignments, and schedules were weighted to give more games to divisional opponents:| Central Division | South Division | West Division |
| Kettle Moraine | Kenosha Bradford | Arrowhead |
| Muskego | Kenosha Tremper | Mukwonago |
| Nathan Hale | Racine Case | Waukesha North |
| Oak Creek | Racine Horlick | Waukesha South |
| West Allis Central | Racine Park | Waukesha West |
1997-2009
After a few years of competition, most of the schools in the Central and West Divisions were unhappy with the long travel distances experienced with facing schools in Racine and Kenosha. In addition, the WIAA approved a merger with the Wisconsin Independent Schools Athletic Association to begin in 1997. In the wake of these developments, another round of realignment was approved for the high school conferences in southeastern Wisconsin. Two new conferences were created, and the Southeast Conference lost members to both of them. Six schools joined the Classic 8, and two joined the Greater Metro. The remaining seven schools accepted three new members into the Southeast Conference: two from the Woodland Conference and one from the Southern Lakes Conference. The ten schools of the Southeast Conference were aligned into Northern and Southern divisions:| Northern Division | Southern Division |
| Burlington | Kenosha Bradford |
| Franklin | Kenosha Tremper |
| Muskego | Racine Case |
| Oak Creek | Racine Horlick |
| South Milwaukee | Racine Park |
2009-present
Within a few years after the Southeast Conference was realigned in 1997, the two smallest schools began to voice their displeasure at the long travel distances and competitive imbalance they faced as members. Both schools rejoined their former conferences in 2009, with Burlington returning to the Southern Lakes Conference and South Milwaukee reuniting with the Woodland Conference. The Southeast Conference dropped divisional alignments to compete as a single entity with the reduction to eight members. In 2012, Muskego left to join the Classic 8 Conference after the Kenosha Unified School District added a third high school on the west side of the city. In 2025, Oak Creek left to become members of the Classic 8 Conference, decreasing the Southeast Conference's roster to seven schools.Football-only alignment
In February 2019, in conjunction with the Wisconsin Football Coaches Association, the WIAA released a sweeping football-only realignment for Wisconsin to commence with the 2020 football season and run on a two-year cycle. The Southeast Conference was one of the few conferences in the state that stayed entirely intact after the realignment, but this will no longer be the case for the 2026-2027 realignment cycle. Oak Creek will be joining the Classic 8 and Franklin is aligning with the Greater Metro Conference. Westosha Central will be moving over from the Southern Lakes Conference as a replacement, and with both conferences having seven football members, the Southeast and Southern Lakes Conferences will enter a scheduling partnership. This partnership mandates that one crossover game per school per season must be played, with the results included in the respective schools won-loss record in conference play.List of member schools
