The paper sets up a framework to understand and further research the role of European party federations as governance and Europeanization actors in central and Eastern Europe. The specific case is the European Green Party (EGP) and the members and associated parties in the regions. From preliminary findings, there are discursive, programmatic and organizational changes in the parties of the region. The research can fit into the larger Europeanization literature with so far has engaged only selectively the European Party Federation. Apparently, the EGP is in a unique position. The number of contenders, with their relatively small size and weak electoral performance, makes EGP a power for actor in relation to the CEE parties. In many cases, it acts like a gatekeeper of European governance.
