The Workers Revolutionary Party (Greek: Εργατικό Επαναστατικό Κόμμα (ΕΕΚ), Ergatiko Epanastatiko Komma, EEK) is a Trotskyist communist political party in Greece, taking part in the elections independently,[2] since the departure from Radical Left Front (MERA, ΜΕΡΑ) coalition in spring of 2009.

Another of its publications is Επαναστατική Μαρξιστική Επιθεώρηση (Epanastatiki Marxistiki Epitheorisi, Revolutionary Marxist Review), a theoretical magazine.

The internal crisis of the Fourth International was followed in 1958 by a crisis inside its Greek section, ΚΔΚΕ – Κομμουνιστικό Διεθνιστικό Κόμμα Ελλάδας (Kommounistiko Diethnistiko Komma Elladas, Communist Internationalist Party of Greece) causing the departure of many members that rejected Pabloism and entrism sui generis.

Among them were Trotskyist revolutionaries that were legends for the Greek movement since the 1920s, such as Loukas Karliaftis aka "Kostas Kastritis" or Mastroyiannis – Theotokatos.

The newborn organization published the magazine "Ο Διεθνιστής" ("The Internationalist") and soon started to play a significant role in class war in Greece.

Many members were arrested, prisoned and tortured, but the organization never stop to fight against the dictators illegally through publications, propaganda and by participating in the student revolt of November 1973.
