ABSTRACT : This study aims to analyze the influence of servant leadership and organizational culture on the sustainability of Adiwiyata Schools, with organizational commitment as a mediating variable. The Adiwiyata School Program emphasizes the importance of service-oriented leadership and an organizational culture that supports environmentally friendly behavior. This study used a quantitative approach with a survey method of teachers and education personnel at Adiwiyata schools. The sample size was 240, with proportional random sampling used. Data collection used questionnaires distributed to respondents. SEM PLS was used for data analysis. These findings indicate that school sustainability is not solely determined by government regulations and programs, but also supported by the quality of servant leadership and a solid organizational culture.  Therefore, strengthening servant leadership, internalizing organizational cultural values, and increasing commitment are important strategies to support the sustainability of Adiwiyata Schools.
