A comprehensive bibliometric analysis of gratitude-related literature indexed in the Web of Science (WoS) core collection was undertaken, encompassing 2,982 scholarly documents published between 2009 - 2024 that featured the term "gratitude" in their titles, abstracts, or keywords. The dataset was systematically examined using WoS's native analytical tools and VOSviewer (version 1.6.16) to identify publication trends, citation networks, and collaborative patterns, revealing the United States, Australia, and the United Kingdom as the most productive countries, while highlighting key contributors and influential institutions. Through keyword co-occurrence and thematic mapping, five distinct research clusters were delineated: (1) evolutionary and biological perspectives on gratitude, (2) psychophysiological correlates of gratitude and wellbeing, (3) gratitude interventions within positive psychology frameworks, (4) developmental trajectories of gratitude in youth populations, and (5) mechanistic studies examining mediators and moderators of gratitude's effects. The analysis revealed a predominant Western bias in theoretical frameworks and methodological approaches, with particular emphasis on individualistic conceptualizations of gratitude, while simultaneously underscoring significant gaps in cross-cultural research, particularly from Global South perspectives and Indigenous Knowledge Systems. These findings suggest the necessity for future research to incorporate decolonial methodologies, culturally-situated epistemologies, and interdisciplinary approaches that acknowledge gratitude as a biocultural phenomenon, thereby expanding beyond the current constraints of Eurocentric positive psychology paradigms to develop more inclusive and holistic understandings of gratitude across diverse sociocultural contexts.
