This article investigates the impact of citizenship education (Pendidikan Kewarganegaraan) in Indonesia on mitigating vigilantism, a social issue rooted in public distrust of the legal system. The authors argue that effective citizenship education can cultivate civic responsibility and discourage extrajudicial actions by instilling democratic values, empathy, and critical thinking. The study employs a qualitative methodology, using questionnaires to gather insights from university students regarding their perceptions of vigilantism and the role of citizenship education. Key findings indicate that experiential learning methods, such as debates and role-playing, significantly reshape attitudes towards the law and reduce support for vigilantism. Despite challenges like inconsistent curriculum delivery and cultural resistance, the research highlights the potential of citizenship education to foster a culture of legal adherence and societal harmony. By enhancing public trust in formal legal institutions, citizenship education emerges as a crucial tool for societal reform, promoting a more peaceful and law-abiding community. This study underscores the necessity of integrating comprehensive citizenship education in schools and community programs to effectively address the roots of vigilantism in Indonesia.
