The tallest building in San Antonio is the Marriott Rivercenter, a 546 ft (166.4 m) tall hotel skyscraper that was built in 1988. However, the city's tallest free-standing structure is the 750 ft (229 m) Tower of the Americas. It is the second-tallest observation tower in the United States.

San Antonio's first high-rise construction boom occurred in the 1920s. This period saw the completion of the Emily Morgan Hotel, the Milam Building, and the Tower Life Building, each of which became the tallest building in the city. The 280 ft (85 m) Milam Building was the first high-rise air-conditioned office building in the United States, while the 404 ft (123 m) Tower Life Building (originally the Smith-Young Tower) is notable for its late gothic revival architecture and its brick and terracotta octagonal exterior. After the onset of the Great Depression, skyscraper construction slowed. The Tower Life Building remained the city's tallest building for nearly 60 years.

High-rise development resumed in the late 1950s, and continued steadily for the next two decades. The famous Tower of the Americas was built for the city's world's fair, HemisFair '68. The structure was the tallest observation tower in the country until 1996, when the Stratosphere Tower in Las Vegas was completed. The 1980s was the most productive decade for San Antonio's skyline, and saw the construction of the Marriott Rivercenter and the city's second tallest building, the Weston Centre. Since 2000, there have been two main periods of high-rise development. The first occurred in the late 2000s, and saw the addition of Grand Hyatt San Antonio, the city's third tallest building. The second has been ongoing since the late 2010s. The Frost Tower, the new headquarters for Frost Bank, was completed in 2019 and features a distinctive glass crown.^[3][4] 300 Main, the city's tallest residential building at a height of 387 ft (118 m), was completed in 2024 amidst an apartment boom.^[5][6][7][8]

Most of San Antonio's tallest buildings are located in downtown, surrounded by Interstate 35 to the west and Interstate 37 to the east. The San Antonio River runs through downtown, and a section of the river forms the San Antonio River Walk in the center of downtown. Several prominent high-rises are situated along the river walk, including the city's four tallest buildings, the Drury Plaza Hotel, and the Hilton Palacio del Rio. A triangle-shaped "viewshed" around the Alamo has limited the height of buildings around the fortress since 2003.^[9][10] There are ten buildings taller than 200 ft (61 m) elsewhere in the city, the tallest of which is The Towers at Park Lane. The furthest of these towers is Tesoro Headquarters, which sits outside Loop 1604.
