2023 Liga 1 (Peru)

The 2023 Liga 1 de Fútbol Profesional (known as the Liga 1 Betsson 2023 for sponsorship reasons) was the 107th season of the Peruvian Primera División, the highest division of Peruvian football. A total of 19 teams competed in the season, which began on 3 February and ended on 8 November 2023. The season was originally scheduled to begin on 21 January, but the first two matchdays were postponed due to the 2022–2023 Peruvian protests. The fixtures for the season were announced on 30 December 2022.

Universitario were the champions, winning their twenty-seventh league title after defeating Alianza Lima in the two-legged final with a 3–1 aggregate score. Alianza Lima were the defending champions, having won back-to-back titles in 2021 and 2022.

Teams
19 teams took part in the league in this season: the top 16 teams from the 2022 tournament, plus the 2022 Copa Perú champions Deportivo Garcilaso, the Liga 2 champions Cusco and Unión Comercio, the winners of the promotion/relegation play-off. The promoted teams replaced Ayacucho, Universidad San Martín and Carlos Stein, who were relegated at the end of the previous season.

Playoffs
As the champions of the Apertura (Alianza Lima) and Clausura (Universitario) tournaments were also the top two teams in the aggregate table, both teams qualified directly to the final, omitting the semifinal matches (Regulations Article 7.3.1.8). Alianza Lima had the chance to decide the order of legs as the finalist better placed in the aggregate table.

Second leg
Universitario won 3–1 on aggregate.
