Spanish Civil War veteran Michael O'Riordan was the secretary other notable members included Jim Savage and Gerry Higgins (who like O'Riordan had been a member of the Liam Mellows branch of the Irish Labour Party), other notable members were Derry Kelleher, Kevin Neville and Máire Keohane-Sheehan.

The Cork Socialist Party ran a number of public lectures on topics like 'science and socialism', 'on the Jewish question', 'Cork Pioneers of Socialism (William Thompson)'.
