Tulsa is the second largest city in the U.S. state of Oklahoma, with a metropolitan area population of approximately 1 million. Tulsa is the site of 28 buildings that stand taller than 200 feet (61 m), 12 of which are taller than 300 feet (91 m) as of 2026. Four skyscrapers reach a height of 492 feet (150 m). On these metrics, Tulsa ranks as the largest skyline in the state, ahead of Oklahoma City. The tallest building in Tulsa is the BOK Tower, which rises 667 feet (203 m) in Downtown Tulsa and was completed in 1975. BOK Tower is the second tallest building in Oklahoma, after Devon Energy Center in Oklahoma City. Tulsa and Oklahoma City contain the majority of Oklahoma's tallest buildings.

Among the earliest high-rises to be built in Tulsa was the 16-story Cosden Building in 1918, regarded as the first skyscraper in Tulsa. The city went through an early building boom in the 1920s, resulting in the construction of notable high-rises such as the Mayo Hotel, the Mincks-Adams Hotel, the Thompson Building, and the Philtower, alongside an addition to the 320 South Boston Building, bringing it to a height of 400 ft (122 m), then the tallest in the city. There were no high-rises built in the 1930s and 1940s. The First National Bank Building, completed in 1950, marked the first modern style high-rise in the Tulsa. The 1960s saw an increase in skyscraper development. The Bank of America Center took the title of the city's tallest building in 1967, while two notable residential towers were built south of downtown: Liberty Tower and the cylindrical University Club Tower.

This trend continued into the 1970s as the BOK Tower was completed in 1975, remaining the tallest building in the city since. That same year also saw the completion of First Place Tower. The CityPlex Towers are a complex of three high-rise buildings constructed in south Tulsa between 1979 and 1981. Conceived of by televangelist Oral Roberts, the complex was initially intended to be a major charismatic Christian hospital. The tallest of the towers rises 648 ft (198 m) and is the second tallest building in Tulsa. The early 1980s saw a surge in high-rise construction, including the addition of a 20-story structure to the Cosden Building (now the Mid-Continent Tower), bringing its height to 513 ft (156 m), the fourth tallest in the city. Skyscraper construction halted in the mid-1980s following the city's oil bust. Since then, few high-rises have been built in Tulsa, leaving the city's skyline relatively unchanged in the following four decades.

Most of Tulsa's tallest buildings are situated in Downtown Tulsa, which is bounded by Interstate 244 to the north and west, and U.S Route 75 to the south and east. Besides the CityPlex Towers, other buildings taller than 200 ft (61 m) located outside of downtown include the Warren Place complex, the River Spirit Casino Resort, and Remington Tower, which was heavily damaged by the 2017 Tulsa tornadoes and was converted into apartments in 2024.
