Holy Trinity Church is a historic church of the Roman Catholic Archdiocese of Chicago located at 1118 North Noble Street. It is a prime example of the so-called 'Polish cathedral style' of churches, in both its opulence and grand scale. Along with such monumental religious edifices as St. Mary of the Angels, St. Hedwig's or St. John Cantius, it is one of the many Polish churches that dominate over the Kennedy Expressway in the Pulaski Park neighborhood of Chicago.

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.
