The current study maps the research landscape on fake news and misinformation, analyzing 560 works from 2005–2025 using bibliometric tools like Biblioshiny and VOSviewer. Findings reveal a sharp post-2016 increase in studies—linked to global events like the U.S. election and COVID-19—and highlight the central role of social media in shaping trust. The U.S. and Spain lead in output, with notable contributions from Brazil. Despite progress, research gaps persist in non-Western and non-English contexts. The study calls for inclusive, interdisciplinary strategies to counter misinformation globally.
