Introduction: a peer facilitator is a student appointed to help peers with learning difficulties, usually from a higher-achieving group. This approach benefits both facilitators and participants by enhancing knowledge, skills, and confidence. Peer-led programs improve academic performance, self-concept, and behavior. Research highlights their effectiveness in education and health, emphasizing the need for proper training and support.Peer facilitation has gained attention as an alternative approach in health, education, and social programs. Despite extensive research, gaps remain in its theoretical and methodological foundations.Method: This study employs bibliometric analysis to explore trends, key themes, and research gaps in peer facilitation from 2014–2024. Using Biblioshiny-R and VOSviewer, it maps academic contributions and emerging interdisciplinary connections. The study involved a bibliometric analysis of 249 publications on the subject listed in the Scopus database from 2014 to 2024. The bibliometric procedure evaluates research performance and progress within an international impact framework, while Biblioshiny-R and VOSviewer visualize overall research trends in peer facilitator.Results: This study analyzed 249 peer-reviewed articles on peer facilitators from Scopus. Publications grew significantly from 2014 to 2024, peaking in 2024. A three-field plot highlights key references, authors, and topics like mental health and youth development. Bradford’s Law identifies BMJ Open and BMC Public Health as core journals. University College London leads institutional contributions. The results of the study show that United State is the country with the most publications related to peer facilitator. Annette W. Burgess and Stuart J. Fairclough are two prominent authors in this field based on the total number of publications and citations. The journal BMJ Open is the journal that has published the most papers on this topic.Conclusions: This paper is useful to academics, organizations, and policy makers in understanding the general picture of the peer facilitation field and allows future researchers to see where this research began and trace its shift over time. Findings highlight their effectiveness in promoting health awareness, enhancing communication skills, and fostering peer support. Future research should explore students’ perspectives and qualitative aspects, such as emotional and social benefits, to deepen understanding of their impact
