St. Hedwig's Church is a historic parish church of the Roman Catholic Archdiocese of Chicago located in Chicago, Illinois. Constructed in the grand Polish Cathedral style, it is one of the many monumental Polish churches visible from the Kennedy Expressway. The church is located at 2226 North Hoyne Avenue.

The Polish cathedral architectural style is a North American genre of Catholic church architecture found throughout the Great Lakes and Middle Atlantic regions as well as in parts of New England. These monumentally grand churches are not necessarily cathedrals, defined as seats of bishops or of their dioceses.
