To conduct bibliometric analysis, VOSviewer and Biblioshiny were utilized to analyze the co-authorship, co-citation, and co-occurrence network analysis of articles published on online education satisfaction between 2011 and 2022. The analysis aimed to show the research status, topics, and future research trends in the field. This paper reports the following findings: (1) There is a booming interest in research on online education in various countries and fields. (2) The most frequently studied target sample is undergraduate students' online education satisfaction; the most commonly used method is structural equation model combined with questionnaire survey; the most studied factors include students' individual factors, information technology tools, and their interaction with others; and the most studied variables include self-efficacy, motivation, perceived ease of use, perceived usefulness, expectation, and social existence. (3) Many fields, such as teacher satisfaction and the construction of new models and tools, remain underexplored. Future research should strengthen international cooperation, promote interdisciplinary research, and explore additional related fields.
