List of tallest buildings in Chicago

Chicago is the third-largest city in the United States, with a metropolitan area of over 9 million people. It is home to over 1,250 completed high-rises,^[5][6] 57 of which stand taller than 600 feet (183 m). As the birthplace of the skyscraper,^[7][8] Chicago has always played a prominent role in their development, and its skyline spans the full history of skyscraper construction. The tallest building in the city is the 110-story Willis Tower (also known as the Sears Tower), which rises 1,451 feet (442 m) in the Chicago Loop and was completed in 1974.^[9][10] Of the fifteen tallest buildings in the United States, five are in Chicago. Chicago's skyline is the second largest in the United States, in North America, and in the Western Hemisphere, after New York City.

The Home Insurance Building, completed in 1885, is regarded as the world's first skyscraper. This building used the steel-frame method, innovated in Chicago; it was originally built with 10 stories, and later expanded to 12, to a height of 180 feet (55 m), an enormous height for the 19th century.^[11][12] Being the inventor of the skyscraper, Chicago went through a series of early high-rise construction booms that lasted from the 1880s to the mid-1930s, during which nine of the city's 100 tallest buildings were completed.^[13] Chicago and New York City were the only cities in the world with large, high-rise skylines during the first half of the 20th century. Chicago then went through an even larger building boom that lasted from the early 1960s to the early 1990s, in which many notable commercial skyscrapers were built, such as the city's fourth-tallest building, the Aon Center, its fifth tallest, 875 North Michigan Avenue (also known as the John Hancock Center), and Willis Tower, which was the tallest building in the world upon its completion until 1993, and the tallest in the United States until 2013. For most of the 20th century until the 1990s, Chicago had the second largest skyline in the world.

A third boom began in the 2000s, which saw the completion of the city's second tallest building, the Trump International Hotel & Tower, and its third tallest, St Regis Chicago, the tallest structure designed by a woman. Chicago leads the nation in the twenty tallest women-designed towers in the world, thanks to contributions by Jeanne Gang and Natalie de Blois. The skyline has expanded into the South Loop with skyscrapers such as NEMA Chicago and One Museum Park, as well as westwards into the West Loop and Fulton Market areas. Wolf Point is home to a number of new developments such as Salesforce Tower Chicago. Other notable new skyscrapers include 110 North Wacker (2020), One Chicago Square (2022), and 1000M (2024). The tallest building under construction is 400 Lake Shore, built on the site of the cancelled Chicago Spire project; it scheduled to be completed by 2027.

The tallest buildings in Chicago are concentrated in the downtown areas of the Loop, Streeterville, River North, the South Loop, and the West Loop. Other high-rises extend north along the waterfront into North Side districts such as the Gold Coast, Lincoln Park, Lakeview, Uptown and Edgewater, bounded by Lake Michigan to the east. Some high-rises also extend south from downtown along the waterfront to South Side districts such as Kenwood, Hyde Park, and South Shore, ultimately forming a contiguous area of high-rises that is among the largest in the United States. Chicago's skyline is a cultural icon of the city, and has appeared in a variety of films and popular media.^[14][15]
