​The European Committee of the Regions (CoR) is the voice of regions and cities in the European Union (EU). It represents local and regional authorities across the European Union and advises on new laws that have an impact on regions and cities (70% of all EU legislation).

The CoR works to bring EU citizens closer to the EU. By involving regional and local representatives who are in daily contact with their electorate's concerns, but also by inviting citizens to participate in various events and debates, the CoR contributes to reducing the gap between the EU institutions' work and EU citizens.
