Almirante Brown de Lules

The club was founded on 1 July 1912 as "Club Atlético Almirante Brown". The first uniform kit acquired by the club were the striped black and yellow worn by Uruguayan CURCC (predecessor of current club Peñarol), that were the only available in stores.

On 21 March 1915 the club changed its name to "Almirante Brown Athletic Club" and one year later it affiliated to Amateur Football Association where the team took part of Tercera de Ascenso, the last division of Argentine football league system. It only lasted one season so the club would be inactive since 1919.

In 1921, four dissident members of neighbor club Huracán de San Justo met with some former members of old club Almirante Brown with the purpose of reestablishing the institution. It was finally set up on 17 January 1922 as "Centro Atlético Almirante Brown", being named Segundo Boragno as president of the club. He managed the club until his death in June 1930.

Almirante Brown played football in several regional leagues, winning the first cup in 1926. In 1929 the team won the La Matanza Partido league (named "Copa Adrián Beccar Varela" honoring former president of the Association). In 1931 Almirante Brown acquired the right to participate in the Amateur Argentina de Football to Club Almafuerte (based in Parque Patricios, Buenos Aires), wearing the same name and colors of the "porteño" club. In 1932 and 1933 the club also took part of the championship.

In 1934 the club was noticed that another institution of Adrogué, also named "Almirante Brown", had disaffiliated from the Association. In an assembly held short later, the club decided to return to tournaments using its original name and colors but Almirante Brown was not allowed to take part due to there was no place for new teams. Therefore, the club began a long period of inactivity that extended to 1942, when some young people from Club Juventud Unida promoted the re-opening of the club Almirante Brown. This was finally formalised in April 1942 with the merger of both institutions.

The club affiliated to the Association again, winning two championships and being designed as Buenos Aires Province representative to play the Argentine Amateur championship held in Cañada de Gómez. During the decade of 1940 Almirante Brown also acquired a land to build its headquarters in San Justo. In 1956 the club affiliated to Argentine Football Association filling the vacant left by defunct Deportivo San Justo, merged to Almirante Brown.

In 1956 Almirante made its debut at "Tercera de Ascenso", the fourth division of the league system (current Primera D), winning its first official title that same season.

In 1986 the Association made a restructuring of the lower divisions, creating the Primera B Nacional that became the second division. Almirante Brown did not qualify to play in the recently created league, remaining in Primera B Metropolitana that became the third division after the restructuring. The team was near to promote to Primera División in 1991–92 season when it played the final with San Martín de Tucumán, which finally won the series promoting to the top division of Argentine football.

In 1998 Almirante was relegated to Primera B Metropolitana, returning to the second division in July 2007, after defeating Estudiantes de Buenos Aires 1–0 at Racing Club stadium in Avellaneda. During the match, Almirante Brown supporters throw a bomb to the field, that caused player Cáceres and Cubito lost consciousness. Immediately after that, a big struggle was started by Almirante Brown supporters, throwing seats and other objects to the other part of the attendance.
