St. Laurence High School is a co-educational, STEM-based high school, founded in 1961. Located in the Roman Catholic Archdiocese of Chicago, the school is conducted by the Congregation of Christian Brothers and is named for the Irish Saint Laurence O'Toole. It is located in the southwest Chicago suburb of Burbank, Illinois, and adjacent to the property of the former Queen of Peace High School, a private, all-female Catholic high school which merged with St. Laurence in 2017.
