The learning and teaching process has been transformed into an online learning system due to COVID-19, which affected lecturer and university students. This research investigates students online learning satisfaction amid COVID-19 by focusing on online learning readiness and academic stress toward online learning satisfaction. Approximately 276 bachelor’s students (Mage = 20.36, SD = 2.47) hired using the accidental sampling technique participated in this study from public and private universities. The data was collected using Learner Readiness for Online Learning (? = .89), Student Satisfaction with Online Learning (? = .90), and Stressor Scale for College Student (? = .85) that has been modified into an online setting and translated into Bahasa. The results showed that academic stress partially mediated the relationship between online learning readiness and online learning satisfaction in bachelor students. It is shown that academic stress significantly affected online learning satisfaction, besides online learning readiness. Further theoretical and practical implications of this research are discussed.
