The competition was played as a knockout tournament in its entirety, with the top six teams in the 2018–19 Superliga season receiving byes to the round of 16, and the remaining 20 teams starting the competition in the first round, where they were paired into 10 ties according to their league placement, with the winners advancing to the round of 16. Matchups in all rounds prior to the final were played as two-legged ties, with the team with the best placement in the league season hosting the second leg, whilst the final was played as a single match at a neutral ground. If teams were tied on aggregate in all rounds prior to the final, the away goals rule was used. If still tied, a penalty shoot-out was used to determine the winner. In the final, 30 minutes of extra time would be played if both teams were tied, and if still tied at the end of extra time, the champions would be determined in a penalty shoot-out. As champions, Tigre qualified for the group stage of the 2020 Copa Libertadores, with the runners-up being entitled to a berth to the 2020 Copa Sudamericana. However, that berth was passed to semifinalists Argentinos Juniors since runners-up Boca Juniors as well as the other semifinalist Atlético Tucumán qualified for the Copa Libertadores.
