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.
