Grit, encompassing perseverance and passion for long-term goals, plays a pivotal role in students' academic success. This study aims to explore the concept of grit, its significance in primary education, and effective character education models for instilling grit in Madrasah Ibtidaiyah students. Employing the Systematic Literature Review (SLR) method, this research adheres to PRISMA guidelines to identify, filter, and analyze relevant literature sourced from leading academic databases such as Scopus, Web of Science (WOS), Google Scholar, and Dimension, covering the period from 2014 to 2025. From an initial pool of 219 articles, 13 met the stringent selection criteria for further analysis. The findings indicate that grit substantially influences students' learning resilience, intrinsic motivation, and academic performance. Moreover, effective grit-based character education models incorporate strategies such as goal setting, fostering a growth mindset, and project-based learning. The implications of this study highlight the necessity of integrating grit into character education curricula in Madrasah Ibtidaiyah to cultivate resilient and achievement-oriented students. However, this study acknowledges its limitations regarding the scope of the reviewed literature and the absence of empirical testing of the proposed model, thereby emphasizing the need for further research to assess its effectiveness across diverse educational and cultural settings
