The club was founded on 1 April 1908, in Buenos Aires by a group of anarchists who discussed fighting for better conditions for the working class. That was the reason that originated its first name, Club Atlético Libertarios Unidos, naming José Garrone as its first president. The colors adopted were red with a horizontal black stripe paying tribute to their anarchist ideology. Libertarios Unidos' first field was placed just beside the Defensores de Belgrano stadium, in the corner of Blandengues and Manzanares streets of Buenos Aires. Libertarios Unidos was soon forced to change its name, because the government had prohibited any anarchist expression. So the club was renamed as Sportivo del Norte in 1919.
1920 decade
Sportivo del Norte obtained the promotion to Primera B in 1919 and one year later the team was playing its first match in Primera División, where it finished 8th. In 1924 Sportivo had to leave its field in Blandengues and Manzanares, moving to Colegiales district. The club soon renamed honoring its new home, changing not only its name to "Club Atlético Colegiales" but its uniform colors, which became blue, red and gold. They have remained the club colors up to present days. In 1926 Colegiales registered to dissident body, Asociación Amateurs de Football where the team made a good campaign with a squad nicknamed "Los Fenómenos " due to the skilled players that formed it. Most frequently line-up was: Tauzlet; Rossi, Tachini; Del Corro, Machiavello, Alberico; Martínez, Toscano, Giudice, Granara Costa, Paduano. Nevertheless, when both leagues merged at the end of the 1926 season, six AAmF teams were disaffiliated and all their matches annulled. As a result, those clubs were sent to the second division, named "Primera División-Sección B". In 1928 Colegiales won the second division championship promoting to Primera División. The line-up was: Santiago Sesana; Rossi, Silva; Del Corro, Pausini, Felipelli; Martínez, Toscano, Giudice, González, Coviello.
1930–56
Colegiales had a poor campaign in 1930 and was relegated to Liga Amateur, where the team finished 2nd. After two consecutive seasons finishing 2nd, the team finally won the 1947 championship. The team went through the season unbeaten, with 77 goals scored and only 23 goals conceded. During that year Colegiales played its home games in different venues so the club had forced to move from Villa Martelli. The champion line-up was: Incardona; A. Dardenne, Arrillaga; F. Baloira, Auad, Céspedes; Coudannes, A. Baloira, Cantamessi, Archero, E. Dardenne. In 1948 the club moved to its current sports field of Antonio Malaver and Gervasio Posadas streets in Florida Oeste, Buenos Aires. A new restructuring in Argentinefootball relegated Colegiales to a lower division, until 6 January 1956, when the squad won another title when defeated Los Andes 1–0. Coached by Guido Ugobono, the line-up for that match was: Negri; Álvarez, Cosentino; Pérez, Aragón, Cappano; Fassani, Morales, López, Tognola, Vecino. But Colegiales only lasted one season in Primera B, so the team was relegated again in 1956.
1957–present
Colegiales returned to Primera B after winning the 1992–93 title, defeating Argentino de Quilmes 1–0 in the last game. The team was coached by Rubén Moreno. Colegiales only lasted one season so in 1994 the team was relegated to Primera C again although Cole would return a year later, after winning the Torneo Reducido. Colegiales remained in the division until the team was relegated to Primera C in 2001. In 2002 the team reached the finals to promote to the upper division but was defeated by Deportivo Laferrere. The next year Colegiales finally got the promotion after beating Villa Dálmine, although the club was punished by the riot caused by its supporters in a match against Tigre. The Argentine Football Association punished Colegiales deducting 9 points to the team, therefore it was relegated to a lower division at the end of the season. In 2008 Colegiales promoted to Primera B when beating Justo José de Urquiza. Colegiales made a great campaign in that division, reaching the finals against Deportivo Merlo. In 2011 Colegiales took part in the relaunched Copa Argentina being defeated by Independiente 4–0 in the first stage.
