The 2019 Atlanta United FC season was the third season of Atlanta United FC's existence, and the eleventh year that a professional soccer club from Atlanta, Georgia competed in the top division of American soccer. Atlanta United played their home matches at Mercedes-Benz Stadium. Outside of MLS, the team made their first appearance in the CONCACAF Champions League and the Campeones Cup (beating Club América to become the first MLS team to win the latter) and won the 2019 U.S. Open Cup by beating Minnesota United 2–1. This marked the team's first year without former head coach Gerardo "Tata" Martino, who was replaced with Frank de Boer.
