One Tampa City Center, Modern skyscraper in Tampa, United States.

One Tampa City Center is a 39-story office tower in downtown Tampa's financial district, standing approximately 537 feet (164 meters) tall. The glass and steel structure dominates the skyline and houses multiple corporate offices and financial firms.

One Tampa City Center opened in 1981 as the GTE Building, the second skyscraper built in Tampa after the Park Tower a few blocks away. It stood 537 feet (164 m) tall and was Florida's tallest building until 1984, when the Wachovia Financial Center surpassed it; it remained Tampa's tallest until the Bank of America Plaza was completed in 1986. In 1991 it became the first skyscraper in Florida to install a building-wide recycling system.

The tower's name changed with its main tenant: opened as the GTE Building, it became the Verizon Building, and in 2012 PNC Bank bought the naming rights, effective May 2013. Tenants today include PNC Bank, Verizon, Merrill Lynch, CDW and Cushman & Wakefield, and the lobby serves the law firms and companies occupying the 39 floors.

The tower sits in the heart of downtown Tampa's business core, easily accessible from major pedestrian areas and nearby streets. Its central location makes it a reference point for navigating the surrounding financial district.

In 1991 the building became the first skyscraper in Florida to install a building-wide recycling system. The facade is a dark blue-green glass curtain wall, divided by thin vertical lines into four tall bays of small rectangular panes. The lower section steps back to the left at the base.
