Racing Club (Spanish pronunciation: [ˈrasin ˈkluβ]) is a professional sports club based in Avellaneda, Argentina. The institution is mostly known for its football team, which competes in the Primera División, the top tier of the Argentine football league system. Founded in 1903, the club joined the Argentine Football Association two years later and played its home matches at Alsina y Colón, the current site of its stadium, El Cilindro. Historically, it is regarded as one of the Big Five of Argentine football.

Though mainly a football club, Racing also hosts other sports such as artistic gymnastics, basketball, beach soccer, boxing, chess, field hockey, futsal, handball, martial arts, roller skating, tennis, and volleyball.

The club has won the Primera División 18 times, including an unmatched streak of seven consecutive titles—five of them unbeaten—between 1913 and 1919, becoming the first club in the world to achieve this and the only one in the Americas. It has also won 15 national cups, holding the record for the most titles in the Copa Ibarguren, Copa de Honor MCBA, Copa Beccar Varela, Copa Británica, and Trofeo de Campeones (SAF).

On the international stage, the club has won eight titles—five organised by CONMEBOL and three jointly by the Argentine Football Association and Uruguayan Football Association—. These include the 1967 Copa Libertadores, the 1967 Intercontinental Cup, the 1988 Supercopa Libertadores, the 2024 Copa Sudamericana, and the 2025 Recopa Sudamericana.

In footballing terms, the team is nicknamed La Academia (The Academy) because it was the most successful side during the amateur era, known for a creole style of play that set the standard and taught its rivals how the game should be played. It is also known as El Primer Grande (The First 'Big'), as it was the first of the Big Five to win a league title, a national cup, and an international trophy. Moreover, it was the first Argentine club to win the World Championship (Intercontinental Cup), achieving this historic milestone in 1967.

Its traditional colours are sky blue and white, chosen as a tribute to the flag of Argentina. Its neighbours and main rivals are Independiente with whom it contests the Avellaneda Derby. Nevertheless, matches against the other three members of the Big Five (Boca Juniors, River Plate, and San Lorenzo) are also regarded as classics. Currently has 103,422 active club members.

Racing dates back to 1898, when a group of workers from the old Buenos Aires Great Southern Railway in the municipality of Barracas al Sud—today Avellaneda Partido—founded the Argentinos Excelsior Club. This early team played friendly matches against other local sides, many of which had been formed by British immigrants, and was based on a basic and undeveloped plot of land at Alsina y Colón (Alsina and Colón) streets, near the local livestock market. The site, owned by the railway company, had originally been granted by the local municipality and was later requested by the employees themselves to be used for playing football, a sport that was rapidly gaining popularity in Argentina at the time.

Despite the formation of this early football team, it eventually dissolved and gave way to the emergence of other local entities, notably Argentinos Unidos, American Club, and Sud América Football Club de Barracas al Sud. The latter was officially founded on 12 May 1901 by a group of alumni from the prestigious Colegio Nacional de Buenos Aires. What set Barracas al Sud apart was the distinctive nature of its founding membership, composed entirely of criollos—Argentine-born individuals of European descent—making it the first football club in the country to be established exclusively by native citizens, rather than by immigrants or foreign communities.
