Adolescents are in a developmental phase marked by various physical and psychological changes. The aim of this study is to analyze the influence of physical activity and sleep quality on students’ academic achievement. The research was conducted at MTs Ma’had Al-Zaytun. The method used in this study is a descriptive quantitative approach with a cross-sectional design. The research sample consisted of 86 ninth-grade students selected from a population of 640 students. The results of the study show that: (1) physical activity does not have a significant effect on students' academic achievement, with a significance value of 0.338 (p > 0.05); (2) sleep quality has a significant effect on academic achievement (p < 0.05); and (3) the most influential factor in academic success is sleep quality. This study is expected to contribute to the development of more holistic educational policies that support student well-being.
