The 'Dicocese of Chicago is part of the Episcopal Church in the United States of America, consisting roughly of the northern third of the state of Illinois. It was founded as the Diocese of Illinois by Bishop Philander Chase. In 1877, the southern portion of Illinois became the Diocese of Springfield, and the west central portion of Illinois became the Diocese of Quincy. The original Diocese of Illinois was then renamed the Diocese of Chicago.
In the Anglican Cycle of Prayer prayers are offered for Chicago on May 25.
