77 West Wacker Drive is an office skyscraper in the Chicago Loop in Chicago, Illinois. Completed in 1992, the 51-story building rises to 668 feet (204 m) and contains approximately 944,000 sq ft (87,700 m2) of interior space. It was designed by Bofill Taller de Arquitectura.
The building was originally known as the RR Donnelley Building, reflecting its primary tenant, RR Donnelley. The company relocated its corporate headquarters in May 2005, and in 2007 the building was renamed the United Building after United Airlines moved its corporate headquarters there from suburban Chicago. In 2012, United relocated its headquarters to the Willis Tower.
In August 2014, Archer Daniels Midland moved its corporate headquarters to 77 West Wacker Drive from Decatur, Illinois.
