List of schools of the Roman Catholic Archdiocese of Chicago
The following is a list of schools operated by the Roman Catholic Archdiocese of Chicago, which covers Cook and Lake counties, followed by a list of former high schools closed after 1959 and former K-8 schools closed after 1983. In 1985 Joseph Bernardin, then the head of the archdiocese, stated that as costs increased to operate Catholic schools, it was likely merging or closure would result. In 1990 Bernardin stated that 18 schools were to close that year. He suggested that some parishes may change from having their own schools  to having joint schools with other parishes, or regional schools. Ultimately 25 schools closed in 1990.
