2018–19 Argentine Primera División

The 2018–19 Argentine Primera División - Superliga Argentina (officially the Superliga Quilmes Clásica for sponsorship reasons) will be the 129th season of top-flight professional football in Argentina. The season will begin on 10 August 2018 and will end on 8 April 2019. Boca Juniors will be the defending champions.

Twenty-six teams will compete in the league, twenty-four returning from the 2017–18 season and two promoted from the 2017–18 Primera B Nacional (Aldosivi and San Martín (T)).

Four teams (Temperley, Olimpo, Arsenal and Chacarita Juniors) were relegated to the Primera B Nacional Championship in the previous tournament.

Competition format
The tournament will be contested by 26 teams. It will begin on 10 August 2018 and will end on 8 April 2019. Each team will play the other 25 teams in a single round-robin tournament. The additional match against the main rival team in the so-called "Fecha de Clásicos" will once again be omitted in this season. From 14 April to 26 May 2019, the Primera División teams will play a new competition named the "Copa de la Liga".

Relegation
Relegation at the end of the season is based on coefficients, which take into consideration the points obtained by the clubs during the present season and the two previous seasons (only seasons at the top-flight are counted). The total tally is then divided by the total number of games played in the top flight on those three seasons and an average is calculated. The four teams with the worst average at the end of the season are relegated to Primera B Nacional.
