The Historic Michigan Boulevard District is a historic district in the Loop community area of Chicago in Cook County, Illinois, United States encompassing Michigan Avenue between 11th (1100 south in the street numbering system) or Roosevelt Road (1200 south), depending on the source, and Randolph Streets (150 north) and named after the nearby Lake Michigan. It was designated a Chicago Landmark on February 27, 2002. The district includes numerous significant buildings on Michigan Avenue facing Grant Park. In addition, this section of Michigan Avenue includes the point recognized as the end of U.S. Route 66. This district is one of the world's best known one-sided streets rivalling Fifth Avenue in New York City and Edinburgh's Princes Street.

The one-sided street feature is due in large part to the legal battles of Aaron Montgomery Ward with the city over cleaning up the park and removing most of the structures in it. Ward opposed the development of Grant Park with public buildings along the lakefront except for the Art Institute of Chicago Building. Eventually, Ward's ideas were adopted by Daniel Burnham in his Plan of Chicago, which called for "insured light, air, and an agreeable outlook" along the Grant Park street frontage. The preservation of the lakefront view has inspired architects to create an architectural cornucopia of designs along the "streetwall". At no point is Michigan Avenue currently called Michigan Boulevard, but prior to the Great Chicago Fire of 1871, the street was officially known as Michigan Boulevard and often referred to as "Boul Mich". As recently as the 1920s, North Michigan Avenue (especially the Magnificent Mile) was referred to as "Upper Boul Mich". Paris' Boulevard Saint-Michel is the original Boul Mich. The district has changed over the years as various architectural designs have evolved to complement it. The boulevard was widened between 1909 and 1910 causing the Art Institute of Chicago Building to have to move the lions guarding its entrance back 12 feet. At that time, the Jackson Boulevard and Michigan Avenue intersection (the end of route 66) was known as "route center". Also at that time, the
