The 2020 Taça de Portugal final was the final match of the 2019–20 Taça de Portugal, which decided the winner of the 80th season of the Taça de Portugal. It was played at the Estádio Cidade de Coimbra in Coimbra, between Benfica and Porto.

The Taça de Portugal is an annual association football competition and the premier knockout tournament in Portuguese football. For sponsorship reasons, it has been known as Taça de Portugal Placard since the 2015–16 season. Organised by the Portuguese Football Federation since it was first held in 1938, the competition is open to professional and amateur clubs from the top-four league divisions. Matches are played from August–September to May–June, and the final is traditionally held at the Estádio Nacional in Oeiras, near Lisbon. The winners qualify for the Supertaça Cândido de Oliveira and the UEFA Europa League.
