This article provides the framework for the contributions to this special issue. It first puts the theme into context and outlines the main issues that justify further analytical engagement with European Union (EU)–North Atlantic Treaty Organization (NATO) relations to the extent we propose here. We then provide some historical background to frame the discussion, and in doing so also outline the current state of interaction between the EU and NATO. We then briefly contextualise the changing strategic environment shaping the relationship, including recent proposals to implement their declared “strategic partnership”. This introduction then presents an overview of the existing literature to set the stage for a renewed look at the research agenda that has emerged over the last two decades. We close with an outline of the individual contributions to this special issue, which are presented in two sections: one focusing on theoretical and conceptual approaches to the study of EU of EU–NATO relations, and one on the inter-organisational relationship in practice, followed by a concluding synopsis and outlook.
