The Socialist Workers' Party (Partido Socialista dos Trabalhadores, PST) was a Portuguese political party founded in 1980 (by dissidents of the Revolutionary Socialist Party) and dissolved in 1981.

It was the Portuguese organisation of the Fourth International (linked to the Parity Committee, an attempt to unify the "Lambertist" and "Morenist" factions of Trotskyism and to the Bolsheviks faction), proletarian and revolutionary, with the objective of establishing a dictatorship of the proletariat through the abolition of capitalism.

It stood in a single election, in coalition with the Workers' Party of Socialist Unity (POUS), for the 1980 Portuguese legislative election.
