List of tallest buildings by U.S. state

The following is a list of the tallest buildings by U.S. state. Forty are in their respective state's largest city and 18 are in their state's capital city. The tallest building in the U.S. by architectural height is currently One World Trade Center in New York, which is approximately 1,776 feet —more than the combined heights of the tallest buildings in Wyoming, Vermont, Maine, South Dakota, Montana, North Dakota, New Hampshire, and West Virginia. Many are attributed to banks: three to JPMorgan Chase and U.S. Bancorp, and two to Wells Fargo and Bank of America.

These future buildings, if completed, would overtake the title of the tallest building in their respective states.

The building heights compared here are calculated from the ground level to the architectural top. Only continuous occupiable space is included. Non-freestanding structures, observational towers, and communication towers are excluded (North Dakota boasts the largest guyed mast structure in the world), as are antennas extending from the structure top. However integral spires are included, facilitating One World Trade Center to be considered taller than Willis Tower. The Council on Tall Buildings and Urban Habitat is considered the arbiter for any dispute. For more information, see building heights.
