BancFirst Tower, Office tower in downtown Oklahoma City, United States

BancFirst Tower is a 36-story office skyscraper at 100 North Broadway Avenue in downtown Oklahoma City, completed in 1971. It rises 152.4 meters (500 feet), making it the second tallest building in the city and the sixth tallest in Oklahoma. Its facade was replaced with bright blue glass during renovations that began in 2020 and were completed in 2023.

The structure was completed in 1971 under the name Liberty Tower and underwent several name changes as different banks took ownership over the decades. BancFirst acquired it in 2018, establishing the name it carries today.

The Petroleum Club of Oklahoma City operates from within this building, serving as a gathering place for business leaders in the energy sector. The structure reflects Oklahoma's deep ties to the oil industry and remains central to the city's economic identity.

The tower is easily identifiable in the downtown skyline and functions as an office building for various companies. Visitors should know that this is a private business building and access to office areas may be restricted to tenants and authorized personnel.

The USS Oklahoma anchor once stood on the Park Avenue median between the tower and the Skirvin Hilton Hotel; it was later moved to 12th Street and Broadway, so it is no longer at the tower. The battleship, sunk at Pearl Harbor on December 7, 1941, suffered casualties second only to the USS Arizona.
