This article lists political parties in Portugal. The Portuguese political scene has been dominated by the Socialist Party and the Social Democratic Party since the 1974 Carnation Revolution, although the CDS - People's Party has been present in some governments and the Portuguese Communist Party in coalition with The Greens holds the presidency of several municipalities.
The parties, as of 2019, represented in the Assembly of the Republic are the Socialist Party (108 MPs), the Social Democratic Party (79 MPs), the Left Bloc (19 MPs), the Communist Party (10 MPs), the CDS - People's Party (5 MPs), the People-Animals-Nature (4 MPs), the Ecologist Party "The Greens" (2 MPs), the CHEGA (1 MP), and the Liberal Initiative (1 MP). LIVRE also elected one MP but later withdrew its political representation, thus making Joacine Katar Moreira an independent MP. Several other parties are represented in the legislatures of the autonomous regions, the Legislative Assembly of the Azores and the Legislative Assembly of Madeira.

This list presents the parties and coalitions of the current Third Republic that were once recognized by the Portuguese Constitutional Court but ceased to exist. It is organized by political spectrum and alphabetical order (in Portuguese).
This list includes the defunct political parties that never reached the Third Republic, in chronological order.
Although the Estado Novo was a dictatorship, with the National Union being legally the only party, the opposition was sometimes allowed to compete in (sham) elections; other parties were constituted underground or in exile.
