The Portland Building, alternatively referenced as the Portland Municipal Services Building, is a 15-story municipal office building located at 1120 SW 5th Avenue in downtown Portland, Oregon. It opened in 1982 and was considered architecturally groundbreaking at the time. The distinctive look of Michael Graves' Portland Building, with its use of a variety of surface materials and colors, small windows, and inclusion of prominent decorative flourishes, was in stark contrast to the architectural style most commonly used for large office buildings at the time, and made the building an icon of postmodern architecture. The building currently houses offices of the City of Portland.
