The Taça da Liga (Portuguese pronunciation: [ˈtasɐ ðɐ ˈliɣɐ]), known outside Portugal as Portuguese League Cup, is an annual club football competition organised by the Liga Portuguesa de Futebol Profissional (LPFP) for teams competing in the top two tiers of Portuguese football – the Primeira Liga and Liga Portugal 2. Unlike Portugal's other domestic cup competition, the Taça de Portugal, the winners of the Taça da Liga do not qualify for European competitions.
The Taça da Liga was established in the 2007–08 season, thus becoming the third official competition for professional clubs in Portugal, after a proposal by Sporting CP and Boavista was approved by LPFP members on 28 November 2006. For sponsorship reasons, it is currently known as Allianz Cup (with the English word cup).
Benfica are the most successful team in the competition, having won eight trophies (four of which consecutively between 2009 and 2012). They are the current holders, after defeating arch-rival Sporting CP in the 2025 final.
