Marshall Field's was an iconic Chicago, Illinois, department store that grew to become a major chain before being acquired by Cincinnati-based Federated Department Stores on August 30, 2005.

The former flagship Marshall Field and Company Building location on State Street in The Loop of downtown Chicago was officially renamed Macy's on State Street on September 9, 2006, and is now one of three national Macy's flagship stores — one of two within the company's Macy's East retail division alongside its New York store at Herald Square. Initially, the State Street store was the lead store of the Macy's North division, immediately following the merger.
