The Eastern Suburban Conference is a former high school athletic conference in Wisconsin, originally formed in 1969 and disbanding in 2001. With the exception of the conference's two private schools, all members belonged to the Wisconsin Interscholastic Athletic Association and were located in south central Wisconsin.
Waterloo joined the Eastern Suburban Conference from the Capitol Conference in 1977,[4] and two years later, Queen of Apostles High School left the conference after it was closed by the Catholic order (Pallotine Fathers and Brothers of Milwaukee) that ran the school.[5] They were replaced in 1980 by Dodgeland, making their return to the Eastern Suburban after ten years of competition as members of the Flyway Conference.[6] Palmyra-Eagle would leave the Eastern Suburban to join the Rock Valley Conference in 1990,[7] and Lakeside Lutheran would make their exit in 1995 for the Capitol Conference.[8] The Eastern Suburban Conference would end its run in 2001 with three schools (Cambridge, Marshall and Waterloo) joining the Capitol Conference and the remaining five (Deerfield, Dodgeland, Hustisford, Johnson Creek and Williams Bay) joining with the Dual County Conference to create the new Trailways Conference.[9]
