Atletico GO

On 2 April 1937, Nicanor Gordo and Joaquim Veiga founded the club, starting football in the newly founded city of Goiânia. Gordo and Veiga left the newly founded club in 1938, and joined Goiânia EC, which was another new club.

In 1944, the club competed in the first Campeonato Goiano, which was also the first official football championship in the state, and was contested between five clubs from Goiânia. The other teams were Goiânia, Vila Nova, Goiás and Campinas. Atlético Goianiense won the competition for its first title. In 1957, the club won the state championship without losing a match, also winning the Torneio dos Invictos, played in the same year.

In 1971, the team won the Torneio da Integração Nacional, beating Ponte Preta in the final. In 1990, after defeating América Mineiro in the penalty shootout, Atlético Goianiense won the Campeonato Brasileiro Série C.

In 2003, Atlético Goianiense finished in the state championship's last place, and was relegated to the following year's second division. In 2005, the club won the Goiás State Championship Second Division, being promoted to the following year's First Division. In 2006, the club finished in second place in the Goiás State Championship First Level, and returned to Serie C. In 2007, they became state champion for the first time in 19 years. The following year, they won the Serie C and were promoted to the 2009 Serie B. In the 2009 Serie B, Goianiense had a good season, finishing fourth and being promoted to the Serie A, for the first time since 1986, and going through four promotions in five years.

In their first season back in Serie A the club finished in 16th place and barely avoided relegation, only finishing above Vitoria on head to head results and sending them down with a 0–0 draw on the last matchday. Although the club barely avoided relegation, highlights of this season were beating third-placed team Corinthians twice, (3–1, 4–3) and two 3-0 victories against Palmeiras.

The 2011 season was better, with the club finishing 13th and qualifying for the 2012 Copa Sudamericana. They were involved in a relegation battle early into the season, but five straight wins in August steered the club away from relegation, and the club ended the season with a big 5–1 victory against America. That season they also won back-to-back state leagues.

In the 2012 Copa Sudamericana, the club was eliminated by Universidad Católica on away goals rule. In the league, the club was relegated and finished 19th.

The club's greatest achievement was in 2016, when they won the Campeonato Brasileiro Série B with two rounds to go.

The club's best international participation was in the 2022 Copa Sudamericana, where they had to play their matches at Estádio Serra Dourada because their main stadium did not meet CONMEBOL requirements. The club qualified for the tournament after finishing 9th in the 2021 Serie A. It was drawn into group F, topping the group with four wins out of six games. In the round of 16, they eliminated three-time Libertadores champions Club Olimpia on penalties, then in the quarter finals eliminated Uruguayan club Nacional 4–0 on aggregate to set up a semi-final with another South American powerhouse, São Paulo. In the first leg on 1 September, Goianiense won 3–1. In the return leg at Estadio Morumbi, São Paulo won 2-0 and tied the aggregate series, sending the match into penalties, where São Paulo won 4-2 and advanced to the final. In the Copa do Brasil the club also had their best ever participation, reaching the quarter finals and being eliminated by finalists Corinthians 4–3 on aggregate. They also won their sixteenth state championship this season, but in the Campeonato Brasileiro the club was not able to replicate the continental success and were relegated again.
