Portage Park located on the northwest side of Chicago, Illinois is one of 77 officially designated Chicago community areas. Portage Park is home to the Polish American Association, the Polish Jesuit Millenium Center, as well as a post of the Polish Army Veterans Association in the beautiful building of the former Irving State bank.

The area is notable for its Six Corners outdoor shopping district, centered at the intersection of Irving Park Road, Cicero Avenue and the diagonal Milwaukee Avenue and for its major park - Portage Park. The name of the park was taken from the major portage linking Lake Michigan and the Chicago River along prehistoric Lake Chicago's shoreline along today's Naragansett Avenue. The present Irving Park Road was so swampy that Indians and trappers used it till 1830 to easily transport their canoes to the West.

In 1840, along with construction of Milwaukee Road (present Milwaukee Avenue), the village of Jefferson (present district of Jefferson Park) incorporated. The area was annexed to the city in 1889 in advance of the World's Columbian Exposition. Much of the area was still largely rural in the early 20th century, and the founding of St. Ladislaus parish in 1914 was key in spurring growth in the area. Nearby Chopin Park is named after Poland's most famous pianist and composer of the Funeral March.

The area is home to a number of architecturally significant churches, among them are St. Pascal's, St. Ladislaus, St. Bartholomew and Our Lady of Victory.
