The Socialist Unity Network was a small network of the far-left in the United Kingdom which was not affiliated with any single political party. It grew out of the Socialist Alliance (SA) in England, and was initiated by several non-aligned members of the SA executive in March 2004.
Members of the network were supporters of Respect – The Unity Coalition and other left electoral initiatives including the Green Party. The main aspect of the network was its now defunct website, which had regularly updated articles from a wide range of socialist perspectives on issues including the possibilities of creating socialist unity.
