Chicago is a large city on Earth, located in the United States of America. The city is located in the northeast corner of the state of Illinois, and sits next to Lake Michigan.

During the early part of the 1920s, organized crime became a powerful fixture in the city of Chicago, to the point that conventional city government nearly fell apart. In the early 1990s, Pocket Books published a book titled Chicago Mobs of the Twenties, detailing the history of the Mob during that time period. A copy of the book later was left on the planet Sigma Iotia II by the Earth ship USS Horizon. The Iotians saw the society depicted in the book as a perfect society, and rebuilt their society along those lines. (TOS episode: "A Piece of the Action")

Rianna Mayweather, chief engineer of the ECS Horizon, was a native of Chicago. She owned a history book about that city, which was one of her prized possessions. (ENT novel: Kobayashi Maru)

This may have been the book Chicago Gangs, seen in the ENT episode: "Horizon".

In 2251, James T. Kirk guessed that Gary Mitchell was either from Chicago or Detroit. He was wrong on both counts, as Mitchell was born and raised in New York City. (TOS - My Brother's Keeper novel: Republic)

In 2374, Benjamin Sisko was surprised to learn that the Captain's Table served Chicago-style pepperoni pizza. (DS9 novel: The Mist)

The Federation starships USS Chicago were named for this city.

Mirror universeEdit

In the mirror universe, Chicago was one of the cities devastated in a brazen attack by alien rebels against the Terran Empire in 2155. Empress Sato I visited Chicago following the attacks, where she was surprised to find the citizens' anger directed at her. (ENT novel: Age of the Empress)
