Digital technologies are considered as a catalyst and important supporter of movement to circularity. 
To find relationship between digital technologies and circular tourism a bibliometric analysis of scientific literature has been conducted in this study. For counting and visualization the authors, keywords and text in the abstracts co-occurrence we have used VOSviewer software. 
The findings shown tight links in the studies between two concepts and how they are interrelated. In this study, we defined the term “circular economy”, the most perspective digital solutions for creation circular tourism, and aspects pertaining to social effect, institutional reforms, and defining the role of the non-profit sector should not be disregarded in the development of circular tourism.
