Flatiron Building, Bank building at Peachtree Street, Atlanta, US.

The Flatiron Building, formally the English-American Building, is an eleven-story Neoclassical skyscraper at 84 Peachtree Street NW in downtown Atlanta. Its wedge-shaped plan fills the triangular block between Peachtree Street NE, Poplar Street NW and Broad Street NW, with the narrow point facing the intersection. Designed by Bradford Gilbert, it is the city's oldest standing skyscraper.

The building was completed in 1897 under the design of architect Bradford Gilbert. It represents an early phase of skyscraper development in Atlanta and remains one of the oldest buildings of its kind still standing in the city.

The building is known as FlatironCity, a hub housing a Microsoft Innovation Center, the Women's Entrepreneurship Institute and more than 20 startups. A statue of boxer Evander Holyfield was announced in 2017 for a spot in front of the building, though the planned location was later changed.

The building occupies the wedge between Peachtree Street NE, Poplar Street NW and Broad Street NW, at 84 Peachtree Street NW. The Rhodes-Haverty Building stands directly across Peachtree at the corner with Williams Street, a useful reference point when approaching on foot through the Fairlie-Poplar district.

The Flatiron Building was completed in 1897, five years before New York's Flatiron Building, and was designed by Bradford Gilbert, a Chicago School contemporary of Daniel Burnham. Since 2017 it has housed the Microsoft Innovation Center, the Women's Entrepreneurship Institute and more than 20 startups under the name FlatironCity. A statue of boxer Evander Holyfield was announced for the site in 2017, but the planned location was later changed.
