This paper examines Polish foreign policy towards the Republic of Belarus in 1990-2020 and how it changed in different periods of time.The relevance of the topic lies in the new periodization of Belarusian-Polish relations in the period 1990-2020, the main criteria of which are events related to the geopolitical changes in the region and related political decisions of the two countries. The analysis of Poland's actions in relation to Belarus was carried out, problematic fields in Polish foreign policy were found, and the tools of Polish influence in the territory of Belarus that exist at the moment were identified. An important point is also the insufficient number of Belarusian works with a geopolitical bias concerning Polish foreign policy in the Belarusian direction, and those that exist rarely go beyond an overview of the events of diplomatic and economic interaction between the two countries.This is the key point in arguing the relevance of the work, which primarily focuses on geopolitical and civilizational factors in the relations between Minsk and Warsaw.
