List of tallest buildings in Seattle

Seattle is the most populous city in the U.S state of Washington and the Pacific Northwest region of North America, with a metropolitan area population of over 4 million. It is home to 53 completed high-rise buildings over 400 feet (122 meters), of which 21 are over 500 ft (152 m) tall. Seattle's skyline is one of the largest on the West Coast of the United States, and is by far the largest in the Northwestern United States. The tallest building in Seattle is the 76-story Columbia Center, which rises 937 feet (286 m) and was completed in 1985. It is currently the 41st-tallest building in the United States, and the tallest building in the state of Washington.

The history of skyscrapers in Seattle began in the late 19th century, with early construction spurred on by money from the Klondike Gold Rush and the Alaska–Yukon–Pacific Exposition. One noteworthy early skyscraper was the neoclassical Smith Tower, a 38-story, 462 ft (141 m) building completed in 1914. It was the tallest building west of the Mississippi River from its completion until 1931. A building boom in the 1920s was followed by a lull in high-rise development from the 1930s until the late 1950s. Seattle's world's fair, the Century 21 Exposition in 1962, contributed to the revival of the city's downtown. The Space Needle, considered the city's most recognizable landmark, was built for the fair as part of the Seattle Center. A 605 ft (184 m) tall observation tower, it was the tallest structure in the city until 1969, as another construction boom began.

The period between the 1960s and the early 1990s would see the addition of many notable commercial skyscrapers. The rate of development was particularly high during the 1980s, during which the city's third and fourth-tallest buildings, 1201 Third Avenue and Two Union Square, were built. Following another downturn in the 1990s, development resumed with the IDX Tower and WaMu Center in the 2000s. In recent years, Seattle has undergone a significant amount of high-rise development. The neighborhood of Denny Triangle has received an influx of residential towers since Amazon's relocation of their headquarters there in 2012, and the skyline has also expanded northwards to South Lake Union and westwards towards Belltown. Seattle's second tallest building, Rainier Square Tower, was completed in 2021.

The majority of tall buildings in Seattle are located in downtown, with several high-rises extending the skyline towards South Lake Union. There are also a number of towers in the area of First Hill, which is separated from the rest of the downtown skyline by Interstate 5. Additionally, there are a cluster of high-rises in University District to the north, as new residential towers have been built near UW Tower since the late 2010s. The suburban city of Bellevue, east of Seattle across Lake Washington, has a skyline of its own.
