East St. Louis School District 189 is a public school district headquartered in the city of East St. Louis, Illinois, United States.
In addition to East St. Louis, the district also serves portions of Canteen, Centreville, and Stites Townships in northwestern St. Clair County.
The non-high school district 202, which included the elementary school districts 182 and 184, was dissolved in July 1956. The area from this district was divided between the East St. Louis school district and the Cahokia Unit School District 187, and therefore the East St. Louis district took students of all grade levels from the former 202 district. The East St. Louis district received around 66% of the students and around 66% of the District 182's assessed valuation. The East St. Louis acquired the three District 182 elementary schools: JMD Brown, Garrison, and LaFayette. The Cahokia district received the remaining students and assessed valuation.
Schools are located in the city of East St. Louis unless otherwise noted.
