Since the Digne Convention in 1991, the literature related to Geoparks has gained a growing interest on the academy’s part, especially in achieving the preservation of geological interest sites through sustainable tourism. This article aims to provide an analysis of the academic research on Geoparks, based on publications in the Scopus database in the period 2002–2020. Bibliometric analysis methods and bibliographic display maps were examined using VOSviewer software. The bibliometric analysis process comprises three phases: (i) Search Criteria and Source Identification, (ii) software and data extraction, and (iii) data analysis and interpretation. The results show geoparks in full growth as a scientific discipline, thanks to the contribution of various authors, institutions, journals, and related topics that confirm the importance of this field of study. Additionally, bibliometric maps lead to an understanding of the intellectual structure of the subject, in which keyword co-occurrence analysis shows six main themes, ranging from ‘UNESCO Global Geoparks’ to ‘Geo-tourism-Sustainable Tourism’. this, combined with maps of co-citation, broadly exhibits this structure and development, showing areas of current interest and potential development, thus offering the latest knowledge on Geopark research worldwide. There is a growing concentration of research on geomorphological heritage and geo-tourism, focusing on methodologies to evaluate the specialities of this type of heritage and define the concept of geo-tourism; there is a great interest especially in the evaluation and identification of geo-site/geo-morphosites which try to eliminate subjectivity in methods and focus on sustainable development of the localities.
