The United States is home to many of the world's tallest skyscrapers; eleven American buildings have held the title of tallest building in the world, and every titleholder from 1890 to 1998 was in the United States.[1] The 10-story Home Insurance Building, built in Chicago in 1885, is regarded as the world's first skyscraper; the building was constructed using a novel steel-loadbearing frame. As of 2009, 6 of the 25 tallest buildings in the world are in the United States; before 1990, the U.S. had had all of the top ten tallest buildings.

As of 2010, the Willis Tower (formerly the Sears Tower) is the tallest skyscraper in the United States, and the fifth-tallest freestanding structure in the world to the antenna and the fifth-tallest building in the world to the roof, with a height of 1,451 feet (442 meters). Prior to the September 11, 2001 attacks in New York City, the twin towers of the World Trade Center occupied the second and third positions on the list below. The North Tower stood at 1,368 feet (417 m), while the South was 1,362 feet (415 m) tall. They are the only buildings which would have qualified for the list which are no longer standing. Chicago and New York have always been the centers of U.S. skyscraper building. Of the top twenty-five buildings, eight are in Chicago and seven are in New York.

The 1776 foot (541 m) One World Trade Center (previously known as the Freedom Tower), scheduled for construction on the former World Trade Center site, was intended to become the tallest building in the United States upon completion in 2013. The Chicago Spire (previously known as the Fordham Spire) a tower under construction in Chicago, Illinois is planned for completion in 2011. This tower would be taller than the under-construction 1 World Trade Center with a height of 2,000 feet (610 m) but it is now on hold, so it is uncertain which tower will be completed first. Other tall buildings that are either proposed or under construction include the American Commerce Center (1,510 feet (460 m)) in Philadelphia, Trans National Place in Boston (1,175 feet (351.8m)), the Signature Tower in Nashville, Tennessee (1,057 feet (322 m)), One Bayfront Plaza (1,049 feet (320 m) and the Empire World Towers (1,022 (312 m) in Miami, Florida and Waterview Tower (1,047 feet (319 m)) in Chicago. If all the proposed buildings are completed at the current projections, nine of the ten tallest buildings in the United States would be located in either New York City (5 - 1 World Trade Center, Madison Square Garden Towers I and II, 2 World Trade Center, and Hudson Place Tower) or Chicago (4 - Chicago Spire, Willis Tower, Trump International, and the Waldorf-Astoria Hotel and Residence Tower), with the lone exception being the American Commerce Center in Philadelphia, which would be number three on the list (behind the Chicago Spire and 1 World Trade Center).

This includes spires and architectural details but does not include antenna masts. An equal sign (=) following a rank indicates the same height between two or more buildings. The "Year" column indicates the year in which a building was completed. Freestanding observation towers, while not habitable buildings, are included for comparison purposes; however, they are not ranked.
