Liga 1 (Peru)

The Liga 1 de Fútbol Profesional (English: "League 1 of Professional Football"), known as Liga 1, and Liga 1 Te Apuesto for sponsorship reasons, is a professional association football league in Peru and the top tier of the Peruvian football league system. It was referred to as the Primera División prior to 2020, and Torneo Descentralizado since 1966 until 2019, when the first teams residing outside the Lima and Callao provinces were invited to compete in the inaugural league national competition.

As of the 2026 season, the league is contested by 18 teams, operating on a system of promotion and relegation determined at the end of the season with the Liga 2. Seasons run from January to December and the league is split into two short tournaments, the Apertura and Clausura. Teams that win each short tournaments face each other in a series of play-offs to determine the league champion at the end of the season. If a team wins both the Apertura and Clausura, they are automatically champion. A total of 34 games, not including the play-offs, are played per team, 17 in both the Apertura and Clausura.

The Peruvian Football League was founded on an amateur basis and organized in 1912 into the two tiers of Primera División and the Segunda División. Editions from 1912 to 1921 were played by clubs based in Lima and Callao. In 1922 the Peruvian Football Federation (FPF) was created and in 1926 it organized its first amateur championship. The Primera División became professional in 1951. In 1966, the first true national league was founded and continues. The league is organized by the Liga de Fútbol Profesional (English: Professional Football League) (LFP) and was formerly organized by the Asociación Deportiva de Fútbol Profesional (English: Professional Football Sport Association) (ADFP).

As of the win by current champion Universitario de Deportes in the 2025 season, the league championship has gone to 21 different clubs, though a majority (74 of 109 championships) have been won by just three clubs: Universitario de Deportes (29), Alianza Lima (25), and Sporting Cristal (20).
