Three First National Plaza is a 57-story office tower in Chicago located at 70 West Madison Street. Completed in 1981, the building is one of the tallest in Chicago at 767 feet (234 m). The 1,439,369-square-foot (133,721.8 m²) building was designed by Skidmore, Owings & Merrill in a sawtooth shape to minimize obstructions it might cause to nearby buildings. The design also allows for thirteen corner offices on lower floors and nine corner offices in the upper regions. The exterior façade is clad in Carnelian granite and features 10-foot-wide bay windows (3.0 m) suggestive of traditional Chicago school architecture.

Three First National Plaza's nine-story atrium used to contain "Large Internal-External Upright Form", a sculpture by Henry Moore. The sculpture was removed and sold in 2016 following a remodel of the lobby. The building features pedway access, and was once connected to Chase Tower by a second-story skywalk.
