The Primera Division (Spanish pronunciation: [pɾiˈmeɾa ðiβiˈsjon]; (English: "First Division"), named Torneo Socios.com (English: "Tournament Socios.com") since 2021 for sponsorship reasons, is a professional football league in Argentina, organised by the Argentine Football Association (AFA).
The Primera Division is the country's premier football division and is the top division of the Argentine football league system. It operates on a system of promotion and relegation with the Primera Nacional (Second Division), with the teams placed lowest at the end of the season being relegated. Since 2020, relegation has been suspended due to COVID-19 pandemic.
With the first championship held in 1891, Argentina became the first country outside the United Kingdom (where the Football League had debuted in 1888, and the Scottish and Irish Football Leagues in 1890) to establish a football league. In the early years, only teams from Buenos Aires, Greater Buenos Aires, La Plata and Rosario were affiliated to the national association. Teams from other cities would join in later years.
The Primera Division turned professional in 1931 when 18 clubs broke away from the amateur leagues to form a professional one. Since then, the season has been contested annually in four different formats and calendars.
The Argentine championship was ranked in the top 10 as one of the strongest leagues in the world (for 1 January 2015 – 31 December 2015 period) by the International Federation of Football History & Statistics (IFFHS). Argentina placed 4th after La Liga (Spain), Serie A (Italy), and Bundesliga (Germany).
