The 2026–27 Sport Lisboa e Benfica season marks the club's 123rd season in existence and its 93rd consecutive campaign in the top flight of Portuguese football. Domestically, the club will compete in the Primeira Liga, Taça da Liga, and Taça de Portugal, while also participating in the UEFA Europa League on the European stage. The pre-season began on 25 June 2026, and the club's European journey kicked off with the Europa League second qualifying round draw on 17 June 2026, followed by draws for the third qualifying round (20 July) and the play-off round (3 August). The league phase draw for the Europa League took place on 28 August 2026, and a notable scheduling adjustment saw the Primeira Liga matchday 3 fixture against Moreirense postponed to 9 September 2026. As of late August 2026, the first-team squad and player statistics were officially recorded, reflecting the early stages of a season where Benfica aims to balance domestic title ambitions with a deep run in European competition.
