Internet is a tool widely used by students to advance online and offline learning, especially during the Coronavirus disease-19 (COVID-19) pandemic. However, overdependence on internet use in the learning process may negatively affect the academic progress of students. Some students delay submitting academic assignments without tangible reasons. Students often use the internet for activities unrelated to academics. This study aimed to investigate the relationship between cyberloafing behavior and academic procrastination of Indonesian students during COVID-19 pandemic. The effect of self-regulated learning in explaining the relationship between cyberloafing behavior and academic procrastination was also discussed. This study used a descriptive study. The data collection technique was the survey method with the help of questionnaires. Sample size for this research was 732 students drawn from both the state and private universities in Indonesia. The results of the study showed that cyberloafing significantly affects students' academic procrastination. Moreover, the relationship between these two variables was moderated by self-regulated learning. This research is expected to provide input to all parties involved in the student learning process and help develop information technology integration in the learning process.
