The Super Essex Conference (SEC) is a high school athletic conference located in Essex County, New Jersey. The conference was formed in 2009 by the New Jersey State Interscholastic Athletic Association and was a result of a larger realignment that swept through North Jersey. The Super Essex Conference was formed by all of Essex County's high schools, the majority of which either came from the NNJIL, Iron Hills, Northern Hills, or Colonial Hills conferences. Several schools were members of either the Mountain Valley or Watchung conferences, while several further were independent. The only school that did not participate was St. Benedict's Preparatory School, which is not part of the NJSIAA's jurisdiction.
