The Fighting Socialist Party of Greece (Greek: Αγωνιστικό Σοσιαλιστικό Κόμμα Ελλάδας, romanized: Agonistikó Sosialistikó Kómma Elládas, Α.Σ.Κ.Ε.

), (ASKE), is a left-wing Greek political party founded in February 1984.

The main core of its founding cadres consisted of members of the organisation committee of PASOK, who immediately after the Greek parliamentary elections in 1981, after which PASOK came to power, protested against it for the violation of its founding proclamations and resigned from their party posts.

Its fundamental views are the struggle for independence from foreign (non-Greek) power blocs, such as the EU and NATO), and for socialism, which the party argues must rely on self-management, the complete respect of personal and political rights, and democracy.

In the 2004 European parliament election, ASKE gathered 11,598 votes which is its best result since its foundation.
