<p>As a complicated phenomenon in an educational context, cyberloafing has gradually attracted researchers’ attention. The current study attempted to explore the association between future time perspective and adolescent cyberloafing by investigating the potential mediating roles of self-control and excessive smartphone use. A sample of 907 adolescents with an age range of 12 to 18 years (<i>M</i>_age = 14.86 years, <i>SD</i> = 1.73) completed a questionnaire on future time perspective, self-control, excessive smartphone use, and cyberloafing. The results showed a significant negative association between future time perspective and cyberloafing among adolescents. Additionally, self-control and excessive smartphone use served as potential mechanisms by which future time perspective related to adolescent cyberloafing. This study enriches the existing research on the factors that influence cyberloafing among adolescents, and contributes to a better understanding of the underlying mechanisms of how future time perspective affects adolescent cyberloafing, providing new insights for the development of interventions.</p>
