The Republic of Croatia, as one of the most important destinations in the Mediterranean, certainly has a very long tradition of this great development opportunity. It adheres to the countries that attract a large number of visitors to the features of their natural space and the richness of cultural and historical heritage. It is emphasized that among the natural attractions are the Adriatic Sea, the most diverse sea coast with many islands, as well as the numerous preserved natural beaches, greenery and forestry. It is precisely this that makes tourism one of the most important drivers of development of the economy in the Republic of Croatia, and hence the emphasis is on the co-financing of EU funds. The main goal of Croatian tourism is to keep an eye out and to ensure its long-term, ie. long-term positive effects of sustainable use of natural and cultural-historical potentials, and active participation in their preservation and development, creating an environment attractive to investors and effective promotion. The aim of this paper is to highlight the importance of EU funds in financing tourism in the Republic of Croatia both in the continental and the coastal Croatia.
