This master’s thesis focuses on tourism in the Brod-Posavina County and the views of the local population on current and future development of tourism in the county. The first part of the paper offers a theoretical framework, that is, an overview of tourism in the world and in Croatia, showing and explaining the state of tourism development in Slavonia with an emphasis on the Brod-Posavina County. The analysis of tourism in the world, divided according to UNWTO categories, indicates that tourism is developed all over the world and that the tourism offer differs greatly from place to place. After the clarification of tourism in the world, the tourism in the Republic of Croatia and its problems, such as seasonality and uneven distribution of tourist traffic and development, were analyzed. Later, this thesis investigates the potential of Slavonia as a tourist destination as well as the tourist resource-attraction offer of the Brod-Posavina County, which was explained in detail. After close inspection, it is evident that the entire area is rich in numerous resources and has potential for the development of tourism in the future. The aim of this work was to determine the attitudes of the local population about tourism in the Brod-Posavina County. In order to do so, a primary empirical research was conducted. A survey was carried out among the local population, and the obtained results were statistically processed. The results of the research show that the local population of Brod-Posavina County recognizes all the potential that the county possesses and sees the possibility of further development of tourism. The rich cultural heritage and gastronomic offer are considered to be some of the main assets of the county. Although dissatisfied with certain aspects such as tourism promotion and youth involvement, the results show that with future development, business improvement and further promotion, the county can become a recognizable tourist destination. Based on the theoretical analysis and the research results, it is evident that Slavonia and the area of Brod-Posavina County represent one of the great potentials for the development and enrichment of the entire tourist offer of the country.
