This paper aims to provide an introductory overview of territorial governance systems in the Nordic capital regions. In doing so, it focuses on the categorisation of various actors that constitute these governance systems. This is achieved through the gathering of information on their principal tasks, scope of action and institutional character. This survey was initially developed within the Nordic Working Group for exchange of experience and knowledge development (Urban policies) and while in progress, the theme was followed up by a seminar on 'Metropolitan Governance in the Nordic Capital Regions' held in Helsinki on the 11th of November 2010. At this seminar, representatives from all 5 Nordic metropolitan regions illuminated governance structures within a particular case study from each Nordic capital region. The lessons and experiences gained from these insights have also been included in this paper.
