2019 Atlanta United FC season

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 FC 2–1. This marked the team's first year without former head coach Gerardo "Tata" Martino, who was replaced with Frank de Boer.

International roster slots
Atlanta had seven International Roster Slots for use at the end of the season. José Hernández did not occupy an international slot while he was on loan to Atlanta United 2. Julian Gressel and Gordon Wild received green cards in May, making them domestic players for MLS roster purposes. On July 1, Atlanta traded an international slot to FC Dallas until the end of the 2020 season as part of a package for Emerson Hyndman's discovery rights. On August 21, Luiz Fernando was added to the senior team roster, occupying Atlanta's last international slot.
