Tourism manifests itself as a multifaceted phenomenon that deeply permeates the social, cultural, economic and ecological aspects of human life. Changes in the way of life of the local population are inevitable. Therefore, the aim of this research was to analyze how the local population of the city of Trogir experiences the multiple impacts that tourism brings and how tourism affects the quality of life of the community. In the first part of the thesis, the theoretical concept of the impact of tourism on the local population and the concept of quality of life were examined. Then, tourism in the city of Trogir was analyzed, i.e. the tourist supply and demand in the city of Trogir. In the empirical part, the views of the local population on the impact of tourism in the area of the city of Trogir were determined based on a questionnaire and conclusions were drawn with respect to the set hypotheses. The results of the conducted empirical part indicate that tourism has both positive and negative impacts on the quality of life of the inhabitants, as the inhabitants perceive both positive and negative impacts of tourism on the local community. The people of Trogir do not currently have a strong aversion to further tourism development, but they believe that they should be more involved in the decision-making process on further development. This research highlights the importance of understanding the complexity of factors influencing local people's perceptions of tourism and the need to adapt tourism development strategies to the needs and conditions of individual communities.
