John Holloway (born 1947) is an Irish Marxist lawyer, sociologist and philosopher, whose work is closely associated with the Zapatista movement in Mexico, his home since 1991.

This conception of state, social form and class struggle, within the Conference of Socialist Economists developed current that ultimately gave rise to the Open Marxism school of thought in which Holloway remained a significant participant.
