Initial expansion proposals At the time the team was announced, Atlanta was the largest metropolitan area without an MLS franchise.
Atlanta Falcons owner
Arthur Blank's AMB Sports and Entertainment Group had submitted a bid for an expansion franchise in 2008, but withdrew the bid in early 2009 due to state and local government budget shortfalls and Blank's inability to find partners to build an appropriate stadium for the proposed team. On July 10, 2010, Dan Courtemanche, MLS's executive vice president of communications, said that despite the bid withdrawal, regular discussions with Blank regarding Atlanta's potential as an expansion market were occurring.
MLS expansion bid On May 31, 2011, the
NHL's
Atlanta Thrashers were sold to
True North Sports & Entertainment, who announced that they would relocate the team to
Winnipeg and rebrand as the
Winnipeg Jets. The Thrashers' relocation helped restart the efforts and talks of bringing an MLS expansion team to Atlanta. In May 2012, while the Falcons' proposed
new stadium was going through the approval process, MLS commissioner
Don Garber cited Atlanta as one of three "intriguing" markets for future league expansion. Additionally, when Blank presented his case for a new stadium at the Falcons' annual meeting with season ticket holders, he stated that an additional benefit of the new stadium was that it could help attract a Major League Soccer franchise and potentially host
World Cup matches. Later that year, in November, Garber said if the Falcons could complete plans for a new stadium, MLS would "try to figure out how an MLS team could be part of their plans."
Rich McKay, Falcons president and CEO, said in 2013 that the team was "open to various options, including [its] ownership of a team or someone else owning a team". and in May 2013, the
Georgia Department of Economic Development board approved $30 million in bonds to finance the land purchase for the new stadium. The stadium was set to open in 2017 and could be configured for professional soccer. Atlanta remained at the top of the list for an MLS expansion team, as Garber, in the December 2013 MLS State of the League address, emphasized that it was a goal to continue to expand in the Southeast, and added, "if we can continue to advance our discussions positively with Arthur [Blank] and the [Atlanta] Falcons, we hope to be able to get a situation finalized so that could potentially be our second team. Orlando being the first, maybe Atlanta or Miami would be the second or the third." In December 2013, Garber said the league was making progress in discussions with the Falcons and that the stadium situation was finalized. Negotiations continued, as Courtemanche said in January 2014 that Atlanta "remains a great prospect for MLS expansion," and in February 2014, Rich McKay confirmed the parties were "far along in negotiations." On April 16, 2014, Blank announced that MLS had awarded an expansion franchise to his group, and the team would begin play in 2017. Atlanta became the second franchise awarded in the Southeastern United States in five months, following the
Orlando City announcement in late 2013. The Southeast had been without an MLS team since the
Miami Fusion and
Tampa Bay Mutiny were dissolved in 2001.
Inaugural season and first championship (2017–2018) Atlanta's first regular season MLS game was played on March 5, 2017, at
Bobby Dodd Stadium with 55,297 in attendance.
Yamil Asad scored the first goal in team history in a 2–1 loss to
New York Red Bulls. A week later, the team registered its first win with a 6–1 away defeat of fellow expansion team
Minnesota United FC. On March 18, 2017, the team registered its first win at home, beating
Chicago Fire, who went down to ten men in the eleventh minute, 4–0 in front of a sold-out Bobby Dodd Stadium. Following its move to
Mercedes-Benz Stadium, the team continued leading the league in attendance and averaged more than 48,000 in its home league matches, breaking records for attendance for a non-doubleheader MLS game and average single-season attendance for a U.S. soccer team. Atlanta clinched a berth in the
playoffs, becoming the third MLS expansion team to do so in their inaugural season, by finishing tied for third place in the
Eastern Conference; due to tiebreaking rules Atlanta was seeded fourth. In its first playoff game, the team faced
Columbus Crew and set a then-MLS attendance record for a playoff game with 67,221 spectators in attendance. After 120 minutes of scoreless action, the match was decided by a
penalty shoot-out, which Columbus won 3–1 to eliminate Atlanta. was

Mexico national team. He was replaced by
Frank de Boer. In the
second edition of the
Campeones Cup, Atlanta defeated
Club América 3–2, winning the trophy and becoming the first club from United States to defeat a Mexican side in the cup match. De Boer led the club to wins in both the
U.S. Open Cup and Campeones Cup, but after beating the
New England Revolution and
Philadelphia Union in the
MLS Playoffs, Atlanta United were eliminated in the conference finals by
Toronto FC. The
2020 season started brightly for United, with two wins in two matches before the season was postponed due to the
COVID-19 pandemic. Following a nearly four-month layoff, United participated in the
MLS is Back Tournament in
Orlando, Florida, losing all three of their matches. Following their elimination from the MLS is Back Tournament, De Boer and Atlanta United mutually agreed to end his relationship with the club. He was replaced on an interim basis by
Stephen Glass, who led the club following the resumption of league play in August.
Decline and subsequent rebuild (2021–2025) At the end of 2020, former
Argentina international defender
Gabriel Heinze signed a two-year contract to be the next head coach. During the offseason prior to the 2021 MLS season, Atlanta United brought in 9 new players including
Santiago Sosa and veteran striker
Lisandro López. On April 6, 2021, United played their first game of the 2021 season, beating Costa Rican side
Alajuelense 1–0 in the away leg of a CONCACAF Champions League tie. The match marked the return of striker

On April 13, Atlanta United again beat Alajuelense 1-0, advancing 2–0 on aggregate to the quarterfinals of the CONCACAF Champions League. In their largest home defeat to date, they lost the first leg of the quarterfinals to
Philadelphia Union on April 27, 2021, by a score of 3–0. On July 18, Atlanta United announced the firing of head coach Gabriel Heinze, after the team hit a club-record eight-game winless streak, with only two wins out of their first thirteen games of the 2021 MLS season. Heinze's interim replacement was Atlanta United assistant coach Rob Valentino. On August 12, former
Mexican international and
Seattle Sounders FC assistant coach

D.C. United on August 21. Valentino remained with the club as an assistant coach. On November 7, Atlanta United clinched a spot in the

Giorgos Giakoumakis with 19 goals. On June 3, 2024, Atlanta United announced the firing of head coach Gonzalo Pineda, after the team lost a club-record 5 consecutive home matches. Pineda's interim replacement is Atlanta United assistant coach
Rob Valentino, who led the team as an interim head coach after Gabriel Heinze was fired in 2021. In the summer transfer window, Atlanta sold
Thiago Almada for a reported fee of $22 million, plus $3 million in add-ons; which broke the transfer record for the MLS. They also sold Giorgos Giakoumakis and
Caleb Wiley, which resulted in Atlanta United having over $50 million to spend in the summer transfer window. Atlanta United finished ninth in the eastern conference, allowing the team to qualify for the wild card round of the
2024 MLS Cup playoffs. After defeating
CF Montréal in the wild card round, Atlanta United upset Supporters' Shield winners

Brooks Lennon,
Bartosz Slisz, and
Noah Cobb. In turn, they would supplement the losses with new players such as
Tomás Jacob and
Lucas Hoyos. ==Colors and badge==
