The Tribune Tower is a 463-foot-tall (141 m), 36-floor neo-Gothic skyscraper located at 435 North Michigan Avenue in Chicago, Illinois, United States. The early 1920s international design competition for the tower became a historic event in 20th-century architecture. Built for Chicago Tribune owner Robert R. McCormick, since 2018 it has been converted into luxury residences and in 2023 won a Driehaus Prize for architectural preservation and adaptive reuse from Landmarks Illinois.
