The Wrigley Building is a skyscraper located at 400–410 North Michigan Avenue on Chicago's Near North Side. It is located on the Magnificent Mile directly across Michigan Avenue from the Tribune Tower. Its two towers in an elaborate style were built between 1920 and 1924 to house the corporate headquarters of the Wrigley Company. Its bright white facade is covered in terra cotta.

The Near North Side is the eighth of Chicago's 77 community areas. It is the northernmost of the three areas that constitute central Chicago, the others being the Loop and the Near South Side. The community area is located north and east of the Chicago River. To its east is Lake Michigan, and its northern boundary is the early 19th-century city limit of Chicago, North Avenue. In 2020 the Near North Side had 105,481 residents, surpassing Lake View as the largest Chicago community area by population. It is also the most densely populated community area and has the second most skyscrapers, after the Loop. With the exception of Goose Island, the Near North Side is known for its extreme affluence, typified by the Gold Coast, Magnificent Mile, Navy Pier, and skyscrapers.
