List of tallest buildings in Denver

Denver is the capital and largest city of the U.S state of Colorado, with a metropolitan area population of 3 million. Denver is home to more than 300 high-rise buildings, 49 of which have a height greater than 300 feet (91 meters) as of 2026. Denver has one of the largest skylines in the Mountain states, with the second greatest number of skyscrapers taller than 492 ft (150 m) after Las Vegas, having eight such buildings. Since 1984, the tallest building in the city is Republic Plaza, a 714-foot (218 m) office skyscraper. It is the tallest building in Colorado. The second-tallest building, 1801 California Street, is 709 ft (216 m) tall, only five feet shorter than Republic Plaza.

The history of skyscrapers in Denver began with the completion of the Equitable Building in 1892; this building, rising 143 feet (44 m) and nine floors, was the first high-rise in Denver. The 20-story Daniels & Fisher Tower became the tallest building between the Mississippi River and the state of California when it was built in 1910. At 325 ft (99 m), it surpassed the tip of the Colorado State Capitol, which was completed less than a decade earlier in 1901. A few more high-rises were built in Denver during the Roaring Twenties, including the AT&T Building in 1929, before the Great Depression put skyscraper development on hold until the 1950s. The city's skyline grew to greater heights during the 1960s and 1970s; oil and gas companies occupied office space in downtown skyscrapers due to proximity to the mountains and the energy fields contained within.

Denver's skyline would see its greatest period of growth in the late 1970s and early 1980s, as the 1970s energy crisis led to a surge in oil and gas prices. From 1974 to 1984, the title of Denver's tallest building changed hands five times. All three of Denver's buildings taller than 650 ft (198 m) were completed between 1982 and 1984: Republic Plaza, 1801 California Street, and Wells Fargo Center, popularly called the "Cash Register Building" for the shape of its roof. Energy prices declined in the 1980s oil glut, abruptly halting Denver's skyscraper boom as vacancy rates increased and the city's population declined. High-rise construction resumed in the 2000s, with major projects such as Four Seasons Hotel Denver and 1144 Fifteenth, the city's fourth and fifth-tallest buildings, while the downtown skyline is expanding northwards towards the Ballpark and RiNo districts.

Most of the city's tallest buildings are located in Downtown Denver. Skyscrapers in downtown are mainly oriented in the area's diagonal grid–with the exception of buildings in North Capitol Hill–as opposed to the rest of the city. There is a smaller and much shorter concentration of residential towers in Cherry Creek, southeast of downtown, and even smaller clusters in Speer and east of Cheesman Park. The Denver Technological Center has several commercial high-rises that are shared between the city and Greenwood Village, a municipality in the metropolitan area. However, the tallest building in the Denver MSA outside of Denver itself is the Rocky Mountain Tower in Glendale, which is 325 ft (99 m) tall.
