The aim of this study is to conduct a bibliometric analysis of articles related to environmental education in early childhood (EEEC). The sub-objectives of the study were to determine the distribution of studies on EEEC by years, the most used keywords, the most cited articles, the most active researchers, the most cited journals and the most active collaborating countries. Bibliometric analysis methods were used in the research. Bibliometric mapping analysis was preferred to provide visual representations of the relationships between the main concepts. The data were obtained from the Web of Science (WoS) database and the 191 articles accessed because of filtering were analysed using VOSviewer software. As a result of the research, it was determined that studies on EEEC have increased over the years. Among the keywords, “early childhood education”, “environmental education” and “sustainability” came to the fore respectively. The most cited study was “Beyond Stewardship: Common World Pedagogies for the Anthropocene”. Prominent journals included “Australian Journal of Environmental Education” and “Sustainability”, while the most influential authors were identified as “Alsina, A.” and “Rodrigues-Silva, J.”. Among the countries, “Australia”, “Canada” and “Brazil” are at the forefront. Encouraging more co-operation and interdisciplinary studies in the field of EEEC will help deepen research in this field.
