The aim of the article is to analyse the impact of the administrative reform implemented in Estonia in 2017 on political participation at the local level. The article verifies the hypothesis assuming that the administrative reform in Estonia has not resulted in significant changes in political participation at the local level, especially in the implementation of new institutions and solutions. The analysis included the legal basis and structure of local self-government in Estonia, the main assumptions of the administrative reform, the institutions of conventional political participation at the local level, and the impact of the administrative reform applicable to political participation arrangements at the local level in Estonia. The research was based on a critical analysis of legislation, documents and literature on the subject. The comparative method has been applied in comparing the solutions in force before and after the administrative reform.
