The Regions Center (formerly the AmSouth Center, before that the AmSouth-Sonat Tower, and originally the First National-Southern Natural Building) is a 390 foot (119 meter) tall, 30 story office tower located at the northwest corner of 20th Street and 5th Avenue North in Birmingham, Alabama USA.

The building served as the corporate headquarters for AmSouth Bancorporation from 1972 until 2006, and Sonat, Inc. and its subsidiaries from 1972 until 2007 when it relocated to the Colonial Brookwood Center. The building now serves as the corporate headquarters for Regions Financial Corporation.

Completed in 1972, the modernist-style skyscraper was designed by Welton Becket & Associates of Houston with Charles H. McCauley Associates serving as the local associated firm. Built as a partnership between First National Bank and Southern Natural Gas Corporation, its original name was the First National-Southern Natural Building. The reflective glass skin stretches between a generously scaled black granite base story and a louvered steel penthouse enclosure. The building is set back from the corner with a raised terrace plaza. A one story banking lobby facing 20th Street closes off the north side of a sunken courtyard which serves the basement-level cafeteria.

During the early 1980s First National changed its name to AmSouth Bancorporation as well as Southern Natural Gas changing its name to Sonat, Inc., and the building was then given its most familiar name the AmSouth-Sonat Tower. In 1986, Sonat announced that it would sell its 50 percent interest in the building to AmSouth and lease back its half of the building, but decided to retain its interest instead.
