The Tribune Tower is a Gothic building located at 435 North Michigan Avenue in Chicago, Illinois. It is the home of the Chicago Tribune and Tribune Company. WGN Radio (720 kHz) also broadcasts from the building, with ground-level studios overlooking nearby Pioneer Court and Michigan Avenue. CNN's Chicago bureau is located in the building. It is listed as a Chicago Landmark and is a contributing property to the Michigan-Wacker Historic District.

In 1922, the Chicago Daily Tribune organized a competition for the 'most beautiful and eye-catching building in the world'. Raymond Hood - who would later build the Rockefeller Center in New York - and John Howell won the first place due to their familiar gothic design and because the building fulfilled the needs of the newspaper best.

The award was very much criticized at the time as the gothic design went against the modernizing trend set by the Chicago School and against the ideas of the more functional European architecture, later known as the International Style, which reduced decorations to the bare minimum. It would in fact be the second place design from Eliel Saarinen and another major contender from Walter Gropius which would greatly influence later skyscraper designs.
