The Mid-Suburban League (MSL) is an Illinois High School Association recognized high school extra-curricular league which includes twelve schools located in the northwest suburbs of Chicago, Illinois. The conference is split up into two divisions for all interscholastic activities. The primary criteria for the separate divisions is geography, with the schools in the West Division being located west of IL Route 53 and the schools of the East Division being east of it. However, the schools of the western division are also larger than the schools of the eastern division.
History
The Mid-Suburban League came into existence for the 1963–64 school year. The MSL and Des Plaines Valley League both broke off from an interim suburban league that dated back several decades. The original members of the MSL were Deerfield High School, Forest View High School, Glenbrook North High School, Glenbrook South High School, Maine West High School, and Prospect High School. Not even a year old, the conference announced expansion for the 1965–66 season with, Wheeling High School, Niles North High School, and New Trier West High School joining as the schools opened. The MSL then announced a realignment for the 1965–66 season when Niles West High School and James B. Conant High School were added, with Deerfield, Glenbrook North, Glenbrook South, Niles West, Niles North, and New Trier West comprising one division, and Forest View, Prospect, Wheeling, Maine West, and James Conant comprising the other.
Just prior to the start of the 1964–65 season, it was announced that Arlington High School would join the league for the 1966–67 season, leaving the West Suburban Conference, and joining the division which included Forest View High School and two soon to open schools: Elk Grove High School and Palatine High School.
