St. Jerome Croatian Catholic Church is an historic church that belongs to the Roman Catholic Archdiocese of Chicago. It is located in the Armour Square neighborhood on the city's South Side, at 2823 South Princeton Street. The church currently performs services in both Croatian and English.
St. Jerome Croatian Catholic Church began in a significantly Croatian-American neighborhood. J. E. Quigley, Archbishop of Chicago, realizing the Croatian Catholic community's need for spiritual guidance and sustenance, requested the Holy See to send a Croatian priest to work among in Chicago. Father Leo Medić OFM, arrived in the U.S. in May 1912 was charged with the responsibility to form the new parish. He began by organizing about 5,000 immigrants from Dalmatia, Banovina, Istria, Slavonia and Bosnia and Herzegovina. The parish's original church and rectory were purchased from German Protestants located on 15th near Wentworth Ave. On December 5, 1912, the Croatian Parish was blessed and opened its doors for public worship.The beginnings of the church were not without some controversy as a dispute concerning whether to call the Church Croatian or Dalmatian required mediation. The Archbishop intervened and proclaimed St. Jerome as a Croatian Church.
As of 1997, the parish had a total of 1,050 parishioners. There were 168 students in the 8-grade grammar school, and the Croatian school had 50 students with 5 teachers.
