The Episcopal Diocese of Northern Indiana, originally called the Episcopal Diocese of Michigan City, is the diocese of the Episcopal Church in the United States of America with jurisdiction over the northern one-third of Indiana. It is in Province 5 and its cathedral, the Cathedral of St. James, is in South Bend, as are the diocesan offices. 
The Episcopal Diocese of Northern Indiana has 36 parishes and missions in 31 counties of northern Indiana. Except for Tippecanoe County, all counties in the state straddling or lying north of 40º 30' North latitude are in the diocese. Fort Wayne is the largest city in the diocese followed by South Bend, Gary, Hammond, and Elkhart. Cities in the diocese with more than one parish are Fort Wayne and South Bend with three each, and Elkhart, Gary and Michigan City with two each.
