The European Union (the EU) is a supranational organization through which members achive common goals. It provides assistance to its members for further tourism growth and improves the competitiveness of the tourism market through numerous support and EU funds. The paper looks at the positioning and competitiveness of the EU members presented in the Travel and Tourism Competitiveness Index (the TTCI), which is published every year by the World Economic Forum. The Republic of Croatia (the RH) became a full member of the EU in July 2013. It is rich in various tourist attractions and destinatios that have a large number of competitive advatanges compared to the other tourist countries. Through its membership, it contributes to the richness and diversity of European identity. Croatian language becomes an equal official language, and more Croatian traditional products are protected in the European market. The RH depends on tourism more than any other EU member, as indicated by GDP data. The RH should develop other areas more intensively, not just tourism. The paper also presents the level of competitiveness of EU members and comparative analysis of the RH. The possibilities of strengthening the country`s tourism competitiveness of the RH following entry into the EU have also been detected, where the analysis observed that the RH is achieving a better position and better results and therefore a higher level of competitiveness. European countries, using there uniqe tourist products and services, can achive a higher level of competitiveness in relation to other countries. Every tourist country, including th RH, should recognize its weaknesses and strengths and strengthen or utilize them. If they recognize their capabilities and use them properly, they occupy a better competitive position according to TTCI.
