The cross-border regions, which are the peripheral regions, are struggling with m troubles. They often include high unemployment, insufficiently developed infrastructure, or inadequate language skills of residents, which are barriers to exploiting the potential of such regions. One kind of remedy is the assumption of the European Union’s regional policy, under which Euroregions are created. These units, constituting a form of cooperation between the regions of the European Union member states, candidate countries, and the regions of their neighbors, with the support of local and regional authorities, constitute support for the competitiveness and development of border areas. The purpose of this study is to verify how people perceive the activity and effectiveness of Euroregions, as well as to try to determine whether they think Euroregions contribute to local and regional development. In this research, an online and self-administered survey was used, with two parts: one related to Euroregions in general, and the other to a specific, selected Euroregion. Despite the fact that the Polish experience has not been as long as in other parts of Europe, the results show that the Euroregions are positively evaluated by people, and they rate them as important for development of the regions.
