Global Citizenship Education (GCE) has emerged as a significant area of research over the last decade, reflected by the substantial volume of scientific publications dedicated to the topic. However, a bibliometric analysis of GCE utilizing the Scopus database has not yet been conducted. This study addresses this gap by analyzing GCE-related articles published in Scopus-indexed journals from 2004 to 2024, employing bibliometric techniques and VOSviewer software. A total of 1,075 articles were examined. The results indicate a marked increase in publication volume since 2016, highlighting a growing interest in GCE—notably, the United States and the United Kingdom lead in publications and international collaborations. The journal Globalisation, Societies and Education is the most prolific, with 70 published articles. Prominent authors include Yemini from Israel, with 540 citations, and Goren from the United Kingdom, with 445 citations. Co-citation analysis revealed distinct research interests, ranging from multicultural perspectives and GCE curriculum development to integrating GCE in the digital era and critically evaluating its objectives and challenges. Moreover, a co-occurrence analysis of keywords identified nine primary research topic clusters, including education for sustainable development, cosmopolitanism, higher education, and international education. The insights derived from this study are crucial for scholars and practitioners engaged in GCE, as they emphasize the importance of fostering international networks and collaborative efforts while encouraging the exploration of more inclusive GCE practices in the future.
