Background: The International Academy for the Study of Tourism (IAST) has undeniably contributed to tourism research. However, the evolution of its members’ research outcomes remains underexplored. Additionally, understanding the academic community’s focus is key to assessing its contribution to knowledge development. This paper, therefore, seeks to examine the scientific publications, publication trends, and metrics of IAST scholars. Methods: The publication patterns of ninety IAST scholars were systematically investigated through a bibliometric and advanced science mapping analysis. This research utilized VOSviewer and the Biblioshiny-R-Studio package for data processing and visualization. Results: This study uncovers dynamic publication trends over the last five years, marked by an acceleration in scholarly production from 2001 to 2012, with an anomalous decrease in 2010. These contributions are widely disseminated across leading academic journals, reflecting a significant intellectual influence through high citation indices and their role as foundational references. Thematically, these scholars consistently foreground central issues such as sustainable tourism development and the protection of vulnerable regions, encompassing cultural and natural heritage. The spectrum of investigated topics spans all levels—from global to local scales—with a multidisciplinary emphasis on tourism economics, governance, tourist consumer behavior, stakeholder roles, and the marketing and sustainability aspects of tourism. Conclusions: IAST scholars’ publications clearly demonstrated trends, impact, and significant terminology in tourism studies. Therefore, academic communities, among others, should broaden their focus, with IAST serving as an example of a community—where scholars produce knowledge-based from diverse perspectives.
