Catholic Diocese of Saginaw

The Catholic Diocese of Saginaw was established on February 26, 1938 by Pope Pius XI. Its territory included 16 counties, carved out the Diocese of Grand Rapids and the Archdiocese of Detroit, in Michigan's "thumb and index finger."

Today, the Saginaw diocese covers 11 counties in eastern mid-Michigan within the Roman Catholic Province of Detroit: Arenac, Bay, Clare, Gladwin, Gratiot, Huron, Isabella, Midland, Saginaw, Sanilac, and Tuscola.

The diocese encompasses 6,955-square-miles of land and is home to an estimated 132,000 Catholics, according to the 2000 Census.
