Workers' Revolutionary Party

A far-left political party in Portugal. It was created on 31 January 1975 and formally registered with the Supreme Court of Justice on 25 March 1975. It followed the Argentine revolutionary Nahuel Moreno's form of Trotskyism, and was in sympathy with, but not formally affiliated to, the reunified Fourth International. The party's stated objective was to organise and lead the working class towards the seizure of power and a socialist revolution, with the ultimate aim of abolishing capitalism and progressively eliminating social classes. The party published the newspaper Combate Socialista (Socialist Combat).

The PRT emerged during the period of intense political radicalisation following the Carnation Revolution. Contemporary accounts identify it as one of several revolutionary left-wing organisations active during 1974–1975, alongside groups such as the Revolutionary Party of the Proletariat and Internationalist Communist League, contributing to the broader shift towards revolutionary socialism in Portugal.

In 1979 the PRT merged with the Internationalist Communist League (LCI) to form the Revolutionary Socialist Party (PSR); the merger was approved by order of the Supreme Court of Justice dated 2 April 1979. The PSR eventually became part of the Left Bloc (BE).
