The Art Institute of Chicago Building houses the Art Institute of Chicago, and is part of the Chicago Landmark Historic Michigan Boulevard District in the Loop community area of Chicago, Illinois. The building is located in Grant Park on the east side of Michigan Avenue, and marks the third address for the Art Institute. The main building was built for the joint purpose of providing an additional facility for the 1893 World's Columbian Exposition, and subsequently the Art Institute. The core of the current complex, located opposite Adams Street, officially opened to the public on December 8, 1893, and was renamed the Allerton Building in 1968.

The Art Institute of Chicago, founded in 1879, is one of the oldest and largest art museums in the United States. It is based in the Art Institute of Chicago Building in Chicago's Grant Park. Its collection, stewarded by 11 curatorial departments, includes works such as Georges Seurat's A Sunday on La Grande Jatte, Pablo Picasso's The Old Guitarist, Edward Hopper's Nighthawks, and Grant Wood's American Gothic. Its permanent collection of nearly 300,000 works of art is augmented by more than 30 special exhibitions mounted yearly that illuminate aspects of the collection and present curatorial and scientific research.
