The paper investigates the impact of EU funds on the Croatian economy. The EU provides investment opportunities in a comprehensive list of projects and programs that cover and integrate almost all business areas. The availability of financial resources from European funds aims to reduce regional disparities between EU Member States, improve the living standards of citizens, living conditions, reduce poverty and wealth disparities. Likewise, the use of these available funds is aimed at improving transport infrastructure, encouraging entrepreneurship, reducing unemployment, using renewable energy sources and encouraging sustainable development. The Republic of Croatia is lagging behind in the efficient withdrawal of available funds from EU funds. The impact of the availability of EU funds in the Republic of Croatia affects the increase of the market, the increase of competitiveness, and the stimulation of total investments. European funds encourage investment activity that leads to an increase in personal consumption, the category that has the largest share in the structure of GDP, which ultimately affects the growth of GDP in the Republic of Croatia. The use of European funds provides a clear and undoubted contribution to economic growth at the national and county level.
