This study aims to describe the role of Intra-School Student Organization (OSIS) activities in shaping students' characters at SMP Unggulan An-Nur Hidayatullah Talok Turen Malang. This study uses a qualitative approach with a case study method. Data collection techniques used are observation, in-depth interviews, and documentation. The data obtained were analyzed through the stages of data reduction, data presentation, and drawing conclusions or verification. The results of the study indicate that OSIS activities play a significant role in supporting the formation of students' characters. Activities such as Basic Student Leadership Training (LDKS), Al-Qur'an recitation, dhuha prayer, commemoration of Islamic holidays, and fundraising for students who experience disasters are effective means of instilling religious values, leadership, responsibility, discipline, and social empathy. OSIS administrators are also actively involved in these activities, so that they learn to organize and become role models for students.
