Introduction. The party-political system of Estonia, with traditionally Euro-optimistic elites leading it, was previously characterized by the presence of a number of so-called “Russian political parties”, which traditionally professed Euroscepticism and criticized the European Union as whole or certain areas of its activities. The purpose of the article is to determine the specific features of the Eurosceptic party discourse of “Russian parties” in Estonia. Materials and Methods. The information basis of the paper consisted of the results obtained using a combination of the comparative method (method of comparative analysis) and the method of discourse analysis. A single case study design was chosen for the paper. The data obtained as a result of using the discourse analysis method made it possible to study the indicators of the Eurosceptic discourse of “Russian parties” and process their programs, manifestos, electoral platforms, as well as statements of their high-ranking representatives. Results. It was revealed that the use of Euroscepticism by the analyzed “Russian parties” when targeting the Russian-speaking diaspora of the state in a number of cases (for example, in case of the Estonian Center Party) has shown some efficacy, allowing it to mobilize the electorate among Russian-speaking citizens. However, it was found that for small marginal “Russian parties” in Estonia this did not demonstrate productivity and benefit, since such efforts did not bring them a significant number of votes in elections at various levels. Most of them, adhering to Eurosceptic protest declarations, were never able to take part in “mainstream politics” of Estonia; thereby they failed to implement their Eurosceptic political agenda. Discussion and Conclusion. The results allow us to conclude that a specific characteristic of the Eurosceptic party discourse of the majority of “Russian parties” in Estonia is its focus on pragmatism for ethnic Russian residents living in this state in the form of concrete results that are useful for them: the desire to improve the existing discriminatory position of ethnic Russian population in Estonia through appealing to Brussels, to solve the problem of so called non-citizens, and, finally, to establish good relations between Estonia and its eastern neighbor state – Russia. The results of this study can find application in the academic activities of universities in our country, may be of interest to political and regional scientists studying political processes in the Baltic States.
