330 North Wabash (formerly IBM Plaza also known as IBM Building and now renamed AMA Plaza) is a skyscraper in downtown Chicago, Illinois, United States, at 330 N. Wabash Avenue, designed by architect Ludwig Mies van der Rohe (who died in 1969 before construction began).

A small bust of the architect by sculptor Marino Marini is displayed in the lobby.

[3] The former IBM Plaza has several design features that are rare in an office building but understandable given its original owner.

Also, given IBM's traditional office hours, large number of workers, and commercial interest in marketing then emerging electronic building control systems (notably the IBM Series/1 and its predecessors), the "banked" intelligent passenger elevator system (with separate all-floor cargo elevators) is significantly over-provisioned for a building of its size and rarely keeps anyone waiting long for service.

[5] The building was declared a Chicago Landmark on February 6, 2008, and added to the National Register of Historic Places on March 26, 2010.
