This list of tallest buildings in the United States ranks skyscrapers in the United States based on official height. The country developed the first skyscrapers and is still home to many of the world's tallest buildings. The world's first skyscraper was built in Chicago, the 10-story Home Insurance Building which was built in 1885 using a novel steel-loadbearing frame. Buildings were soon built much taller using this technique and, for over a century, a U.S. building reigned as the tallest in the world. (See History of tallest skyscrapers) As of 2009, 6 of the 25 tallest buildings in the world are in the U.S,; before 1990, the U.S. had had all of the top ten tallest buildings.

Currently, the Sears Tower is the tallest skyscraper in the United States, and the fourth-tallest freestanding structure in the world. 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. Currently, of the top twenty-five buildings, eight are in Chicago and seven are in New York.

The 1,776 foot (541 m) 1 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 2010. 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 Trump Towers Charlotte, the American Commerce Center (1,510 feet (460 m)) in Philadelphia, the Trump International Hotel and Tower (1,362 feet (415 m)) in Chicago, the Bank of America Tower (1,200 feet (366 m)) in New York City, Trans National Place in Boston (1,175 feet (351.8m)), the Signature Tower in Nashville, Tennessee (1,057 feet (322 m)), 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, Sears 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).

Aon Center in Chicago
Chrysler Building in New York City
Key Tower in Cleveland
