Logan Square is located on the northwest side of Chicago.  The Logan Square neighborhood is centered on the public square that serves as its (and the community area's) namesake. Logan Square proper houses the 3-way intersection of Milwaukee Avenue, Logan Boulevard and Kedzie Boulevard.

The community area of Logan Square is, in general, bounded by the NIRC railroad on the west, the North Branch of the Chicago River on the east, Diversey Avenue on the north, and the SOO Line railroad on the south. The area is characterized by the prominent historical boulevards and large bungalow-style homes.
