The 2019 Liga 2 season was the 74th edition of the second tier of Federación Peruana de Futbol. The season play started in April 2019 and ended on 1 December 2019.
The season has two phases: a home-and-away round-robin phase and a liguilla (league). The team with the most points at the end of the first phase will be crowned 2019 Liga 2 champions and will be promoted to the 2020 Liga 1. The teams who finished 2nd through 7th in the round-robin phase qualify to the liguilla which qualifies two teams to the 2019 Peruvian promotion play-offs. Seeds 4 through 7 play each other. The winners then play the teams in 2nd and 3rd place for a place in the promotion play-offs.[1]

Sport Victoria was disabled mid-season and relegated to the Copa Perú for outstanding debts with the SAFAP.
