Club Atlético All Boys (Spanish pronunciation: [ˈkluβ aˈtletiko ˈol ˈbojs]) is an Argentine sports club based in Floresta, Buenos Aires. The institution is mostly known by its football team, which currently plays in the Primera B Nacional, the second division of the Argentine football league system.
Other sports and activities practiced at the club are basketball, chess, futsal, handball, kick boxing, roller skating, taekwondo, freestyle wrestling, jiu-jitsu and sipalki.
On 15 March 1913, the club was founded by a group of friends. The name "All Boys" reflected the youthfulness of its founders, and followed the Argentine tradition of naming football clubs in English, such as Newell's Old Boys, Boca Juniors, River Plate and Racing Club had done before.
In 1914 All Boys registered to Argentine Football Association and began to play at "División Intermedia" (current Second Division), where they earned qualification to play the Copa Competencia. The team promoted to Primera División in 1922, making its debut in the top division on 11 March 1923 with a 1–0 loss against Temperley. The first official goal in Primera was scored in a 1–1 draw against Porteño. The "Albo" won its first game in Primera in the 3rd fixture, with a 3–1 victory against Progresista.
All Boys disaffiliated from the Association in 1926 but the team returned to Segunda División one year later when both associations merged into one. In 1931, All Boys was promoted a second time, remaining in Primera until 1934 when the Amateur Association joined Professional league and all its teams were relegated.
In 1945 the team went down to the second division for the first time, but in the following year All Boys won the Tercera de Ascenso championship after defeating Justo José de Urquiza 2–1. That season All Boys played 24 matches and scored 91 goals.
In 1950 there was a restructuring in Argentine football that sent many teams to the lower division, alleging that those institutions had their stadiums in poor conditions to host the Primera División matches. One of those teams relegated was All Boys. The following year All Boys won its second championship with a victory over Tiro Federal which brought the "Albo" back to Primera.
In 1972 All Boys hired José Paladino as coach. Under his command, the squad won 11 consecutive games (which remains a record for lower categories), obtaining 29/30 points. Therefore, on 14 October 1972, All Boys became Primera B champion by defeating Excursionistas 1–0 with a goal scored by Benítez.
Some notable players of that team were Valentín Sánchez (top scorer), José Romero (proclaimed as "the best player of the team") and Ángel Mamberto. After promotion to the Primera, All Boys remained eight years in that division, until 1980 when the club was relegated to Primera B.
In the 1982 season, the club was almost relegated to the third division, the Primera C Metropolitana (fourth div. today), after finishing last in the league table, but won the relegation playoff on penalties against Talleres (RE). When the Argentine football system was restructured in 1986 with the addition of the Primera B Nacional, which would become the new second division, All Boys could not qualify amongst the top 8 teams to play the new second division, and as a result was relegated to the Primera B Metropolitana, which became the third division.
In the 1989–90 season, All Boys was very close to achieving promotion back into the second division, but lost the playoff final against Deportivo Laferrere.
For the 1992–93 season Mario Rizzi was hired as the team coach, and he incorporated some players such as Marcelo Blanco, Marcelo Yanino, and Rubén Urquiza. With the help of these transfers, the team made a great campaign and earned promotion to Primera B Nacional. The decisive match was a 2–1 away victory against Defensores de Belgrano, where 25,000 All Boys' supporters attended, which set a new spectator record for the lower categories in Argentine football. This victory gave the club the league title, which also directly promoted it into Primera B Nacional without having to go through the play-offs.
At the end of the 2000–01 season the team was relegated to Primera B Metropolitana again. For the 2002–03 season the club hired Ricardo Caruso Lombardi as coach. The team won 8 consecutive games and qualified to play the Torneo Reducido, which was won by the club, but then lost promotion at the hands of El Porvenir due to a sporting advantage, after having drawn on aggregate. For the 2007–08 season the club incorporated Ariel Zárate, Hernán Grana and Gustavo Bartelt, among other players from different clubs. Former player José Romero was designated as coach. On 6 May 2008, All Boys won another league championship after the 2–0 victory vs Atlanta, which returned "El Albo" to Primera B Nacional.
At the end of the 2009–10 Primera B Nacional season, All Boys finished 4th and qualified to play the promotion playoff in order to gain a place in Primera División. After a 1–1 tie in Floresta, All Boys surprised everyone when thrashing Rosario Central by 3–0 in the second leg played at Estadio Gigante de Arroyito. Therefore, the club returned to the top division of Argentine football after 30 years of playing in lower divisions. In the 2010 Apertura, All Boys had a decent season and finished 8th in the league table, while achieving victories over "big clubs" like Independiente, Estudiantes de La Plata, River Plate, amongst others.
All Boys had their best first division campaign in the 2012 Clausura, when it finished third in the league table, 5 points behind champion Arsenal de Sarandí. The club had the best defensive record as well, only conceding 13 goals. Notable victories included beating Independiente 3–0 at Estadio Libertadores de América and Boca Juniors 3–1 at home with a hat-trick from Emmanuel Perea.
In May 2014 the club was relegated to the Primera B Nacional. In 2018, it was relegated to Primera B Metropolitana, the third division. It gained promotion back into the B Nacional a year later.
