Welcome to McHenry County Illinois

The City of McHenry is a diverse community offering a variety of housing choices, a wide range of employment options, and unparalleled access to recreational activities. Located at the heart of the Fox River just 50 miles northwest of Chicago, McHenry is located in one of the fastest growing counties in the state yet retains its small town charm.

McHenry is conveniently located at the intersection of State Routes 120 and 31 in northeast Illinois, minutes away from Interstates 90, 94 and 43. Our community is served by METRA, Chicagoland Commuter Rail Service, and PACE suburban bus service.

By working together in a combined effort of good will and understanding, we can make the City of McHenry one of the finest places in the United States to live, work and play.
