Tourism significantly contributes to the economic development of the country and as such encourages socio-economic and cultural development. Therefore, in many cities, regions and countries, tourism plays a key role as a strategic foundation of the economy’s GDP. However, this industry is always experiencing the most severe consequences of crises, including the crisis caused by the COVID-19 pandemic that hit the world in early 2020. Therefore, the aim of the final work was to analyze the impact of the pandemic on tourism in the Republic of Croatia, and in order to achieve this goal, the Ilirija Hotel in Biograd na Moru was taken as an example. The figures in tourism from 2019 and 2020 were compared and it was found that the COVID-19 pandemic affected the tourism industry primarily by limiting travel, ie by reducing demand among passengers. At the same time, many countries, including the Republic of Croatia, have introduced travel restrictions in an attempt to curb its spread. With reduced travel opportunities, the restrictions had a negative economic impact on the tourism sector in almost all countries and regions, including the Hotel Ilirija, which, despite everything, managed to make a profit in 2020. Also, despite the partial opening of borders and the abolition of certain measures due to the tourist season in 2020, the tourism industry in the world has multimillion losses, while the decline in tourist arrivals and overnight stays in the Republic of Croatia is recorded in the millions.
