National culture is a term used for a group of people who are adults in the same country, and compared to groups of people from other countries, their expectations of how things should be done and the values related to those expectations are potentially different. Cross-cultural differences are the result of differences in geographical and climatic environment, different history and different political and social values. Individuals differ even within the same culture and sometimes it is very challenging to accept cultural differences. Cultural differences are expressed in the private and business environment. A prerequisite for successful and effective intercultural management is the creation of such an organizational culture in which the tasks, activities and goals of the organization are aligned with the communication and intercultural teams of the organization. Speaking of intercultural differences, the paper compared the national and organizational culture of Finland and Croatia based on a comparative analysis of Hofstede's dimensions of culture. The following hypotheses were put forward and confirmed: Finland and Croatia differ significantly in terms of living standards, and the national cultures of Finland and Croatia differ significantly, and the most pronounced differences are in the acceptance of unequal distribution of power and long-term orientation. In addition, Finland and Croatia differ in their geographical features, educational and political systems, and work and management systems. Consequently, they have very little in common.
