Armour Square, located on the southwest side of Chicago, is one of the 77 officially defined Chicago community areas. Armour Square is also the name of one of three neighborhoods within the community area.

The Armour Square neighborhood, located at the south end of the community area near Comiskey Park, is anchored by Armour Square Park, noted as the site of the 1997 Lenard Clark beating and a later beating of local radio sports personality Mike North after a White Sox game. It lies east of, and is frequently confused with, the Bridgeport neighborhood (Bridgeport is also a community area). The Armour Square neighborhood has a large Italian-American population.
