List of tallest buildings in Austin

Austin is the capital of the U.S state of Texas. Its metropolitan area is the fourth-largest in the state, with 2.5 million people. As of 2026, Austin is home to 65 completed buildings taller than 300 feet (91 m), 18 of which are at least 492 ft (150 m) in height. Austin's skyline is one of the largest in the Southern United States. It has the third most skyscrapers taller than 492 ft (150 m) in Texas, after Houston and Dallas. The tallest building in Austin is Sixth and Guadalupe, a 875 ft (267 m) residential skyscraper built in 2023. It is set to be overtaken by Waterline, a supertall skyscraper that is currently topped out at 1,034 ft (315 m), making it the tallest building in Texas.

With a height of 311 ft (95 m) the Texas State Capitol remained the tallest building in Austin long after its construction in 1888, with the city's central Congress Avenue otherwise lined with single-story buildings through the start of the 1900s. The eight-story Scarbrough Building and the nine-story Littlefield Building, built between 1910 and 1912, are considered to be Austin's first high-rises. The tallest building completed in the first half of the 20th century was the Main Building of the University of Texas at Austin, which holds offices as well as library space for the university. The downtown skyline remained predominantly low-rise until the 1960s, with the addition of the 28-story Westgate Tower in 1966 attracting controversy for its proximity to the capitol. The capitol's height was finally surpassed by the Procore Tower and the Bank of America Center in the 1970s. One American Center, completed in 1984, remained the tallest building in the city for two decades.

Since the 2000s, Austin has been undergoing an unprecedented skyscraper boom, concurrent with rapid population growth in the city and its metropolitan area. The Frost Bank Tower was the first building in Austin to exceed a height of 500 ft (152 m) it was completed in 2004. The boom was momentarily halted in the early 2010s due to the Great Recession, and accelerated in the mid-2010s; around two-thirds of high-rises taller than 300 ft (91 m) in Austin were built after 2014. The majority of new skyscrapers are residential, with the title of the city's tallest building changing hands four more times among residential towers between 2008 and 2023. The city's tech boom has also resulted in more office towers, such as Indeed Tower and the sail-shaped Block 185, which is intended to be fully leased by Google.

Most of Austin's tallest buildings are located in Downtown Austin, sitting directly north of the Colorado River. The Texas State Capitol separates the central skyline from residential towers in the West Campus neighborhood, many of which are inhabited by students attending the nearby University of Texas at Austin. Tall buildings are relatively absent on the southern side of the Colorado River, although a number of them are planned in the South Central Waterfront area. There are also a small number of high-rises in The Domain, a commercial and residential center located in the city's north that is referred to as Austin's "second downtown" In the 2020s, the boom saw the skyline extend eastwards towards Rainey Street Historic District, transforming the character of the neighborhood. Construction on Waterline began there in 2023. When completed, Greater Austin will be the smallest metropolitan area in North America with a supertall skyscraper.
