List of Boca Juniors seasons

The following is a complete list of Club Atlético Boca Juniors seasons since 1908 to present. Competitions contested include domestic and international cups and tournaments.

On 3 April 1905, a group of Greek and Italian boys (more specifically from Genoa) met in order to find a club. The house where the meeting was arranged was Esteban Baglietto's and the other four people who attended were Alfredo Scarpatti, Santiago Sana and brothers Ioannis (Juan) and Theodoros (Teodoro) Farengas from Chios and Konstantinos Karoulias from Samos. Other important founders members include Arturo Penney, Marcelino Vergara, Luis Cerezo, Adolfo Taggio, Giovanelli, Donato Abbatángelo, Bertolini.

In 1925, Boca made its first trip to Europe to play in Spain, Germany and France. The squad played a total of 19 games, winning 15 of them. For that reason Boca was declared "Campeón de Honor" (Champion of Honour) for the 1925 season by the Association.

During successive years, Boca consolidated as one of the most popular teams of Argentina, with a huge number of fans not only in Argentina but worldwide. The club is one of the most successful teams in Argentine football, having won 35 Primera División titles, second only to River Plate with 37, and is the only team that has never been relegated to the second division.
