Academic flow is an important factor characterized by feelings of happiness, increase in concentration and self-control, focus and activities, thereby making students' learning effective. However, exploration of academic flow is still limited, specifically during the global pandemic, which forced students to study from home, including in Indonesia. Therefore, this study investigates the effect of students' academic self-efficacy and social support towards academic flow during the pandemic. Data were collected from 400 college students consisting of 135 males and 265 females. The measurements used in this study are Flow Inventory for Student, College Academic Self-Efficacy Scale (CASES), and Social Provisions Scale (SPS). Multiple linear regression analysis was conducted to test the hypotheses. The result showed that academic self-efficacy and social support positively and significantly influenced college students' academic flow during online learning. This means an increase in academic self-efficacy and social support will likely lead to a rise in academic flow, specifically during the pandemic.
