Subject and purpose of work: Investigation and statistical analysis of tourism flows and of trends observed in Ukrainian-Polish cross-border tourism. The purpose of the study is aiding further crossborder tourism-related cooperation between Ukraine and Poland. Materials and methods: Government and commercial statistics sources. Data analysis methods included literary, analytical, comparative, and quantitative methods. Results: The processes and dynamics of cross-border cooperation between Ukraine and Poland in the field of tourism during 12 years (from 2006 to 2017) have been investigated. The authors analysed data related to tourism flows and determined the primary source-countries of visitors based on the inbound and outbound indicators and the current tourism market trends within this cross-border cooperation. Conclusions: The main trend in the Ukraine-Poland tourism flow over the last decade is the stabilisation of inbound tourism from Poland to Ukraine and a significant increase in outbound tourism from Ukraine to Poland. In the last few years, it has been driven by Ukraine’s focus on Euro-integration.
