2023–24 Taça da Liga

The 2023–24 Taça da Liga was the seventeenth edition of the Taça da Liga (also known as Allianz Cup for sponsorship reasons), a football league cup competition organised by the Liga Portuguesa de Futebol Profissional and contested exclusively by clubs competing in the top two professional tiers of Portuguese football – the Primeira Liga and the LigaPro. It began on 21 July 2023 and concluded with the final in Leiria on 27 January 2024.

Twenty-eight teams, consisting of all teams from the 2022–23 Primeira Liga and Segunda Liga (with the exception of the top six teams in the 2022–23 Primeira Liga), took part in the first round; one-legged ties with no extra-time were played between the sided.

In the second round, the fourteen teams advancing from the previous round were joined by the teams which placed 5th and 6th in the 2022–23 Primeira Liga. Again, one-legged ties with no extra time were played between the sixteen sides.

The third round featured the eight teams advancing from the previous round and the four best-placed teams in the 2022–23 Primeira Liga. The twelve teams were drawn into four groups that were contested in a single round-robin schedule, with each team playing one game at home and one game on the opposition's home.

The four group winners qualified for the knockout phase, which featured single-legged ties, again with no extra time being played. The semi-finals and final were played at a neutral venue, held in Leiria in January 2024.

Tiebreakers
In the third round, teams were ranked according to points (3 points for a win, 1 point for a draw, 0 points for a loss). If two or more teams were tied on points on completion of the group matches, the following criteria were applied to determine the rankings:

 * 3) lowest average age of all players fielded in all group matches (sum of the ages of all fielded players divided by the number of fielded players).

In all other rounds, teams tied at the end of regular time contested a penalty shoot-out to determine the winner. No extra time was played.
