Police in a modern society, faced with numerous security challenges, have an extremely responsible role, which cannot be successfully implemented without cooperation with citizens. Mutual trust is a prerequisite for this cooperation and therefore the functionality of society. On the other hand, values from the very beginnings of sociology have played an important role in thinking and exploring society. They were practiced by almost all the greats of classical (Durkheim, Weber, Parsons ...) but also Croatian (Županov) sociologists. Values play a key role in the development of society and are one of the most important factors in creating attitudes. Therefore, the aim of this paper is to investigate trust in the police in relation to 19 specific values (Schwartz model) among students of post-socialist countries of Southeast Europe (Bosnia and Herzegovina, Montenegro, Croatia, Hungary, Macedonia, Slovenia, Serbia). The survey used a quantitative survey method and the instrument of data collection was an online questionnaire. The sample of 1419 students was used. Descriptive statistics and multiple regression were used in the data analysis. According to the results, the predictors that contribute to trust in the police are conformism-rules, self-direction in thought, self-direction in action, tradition, stimulation, hedonism and humility. The results will contribute to understanding young people's trust in the police in the context of social values in countries where elements of the former and present social, political and economic systems are still intertwined. Given the results and the particular limitations of the research, there is a need for further research into this topic in Southeast Europe.
