Sleep is a vital component in maintaining the physical, psychological, and cognitive well-being of university students. Among Generation Z students, excessive smartphone use may further disrupt sleep quality and negatively impact academic performance. This study aims to examine the relationship between sleep quality and smartphone addiction with the academic performance of Generation Z students at Universitas Indonesia. A quantitative approach with a cross-sectional design was employed, involving undergraduate students as participants. The instruments used included the Pittsburgh Sleep Quality Index (PSQI), the Smartphone Application-Based Addiction Scale (SABAS), Grade Point Average (GPA), and the Academic Performance Scale (APS). Among the 301 participating students, bivariate analysis revealed significant correlations between: (1) sleep quality and GPA (r = -0.200; p < 0.001); (2) sleep quality and APS scores (r = 0.179; p = 0.002); (3) smartphone addiction and GPA (r = -0.134; p = 0.020); and (4) smartphone addiction and APS scores (r = 0.329; p < 0.001). These findings highlight that both sleep quality and smartphone addiction are contributing factors to students' academic performance.
