This paper assesses differences in the financial performances of member businesses of selected cluster organizations in the Czech and Slovak Republics. The first research sample was comprised of member businesses of five cluster organizations operating in the Czech Republic. The second research sample was made up of member businesses of four cluster organizations operating in Slovakia. The aim of the research was to find out whether the financial performance of member businesses in Czech cluster organizations differed from the performance of member businesses in Slovak cluster organizations. The financial performance was assessed using selected financial indicators. The research results showed that member businesses of selected Slovak cluster organizations did not achieve any different financial performance. Finally, the possible causes of this situation are discussed.
