Wells Street Station was a passenger terminal of the Chicago and North Western Railway, located at the southwest corner of Wells Street and Kinzie Street in Chicago, Illinois. It was replaced in 1911 by the Chicago and North Western Terminal on the other (west) side of the North Branch of the Chicago River, removing passenger trains from the Kinzie Street railroad bridge over the river. The Merchandise Mart opened in 1930 on the land formerly occupied by the station.
