Parental phubbing, as a new risk factor for adolescents’ healthy development, has been noticed by scholars. However, few studies have clarified the associations between parental phubbing and adolescents’ proactive and reactive aggression and the potential mediating mechanisms. To address the gaps, the current study explored the longitudinal associations among parental phubbing, self-esteem, and adolescents’ proactive and reactive aggression by using the parallel process latent growth curve model and the cross-lagged panel model. The current study involved 2407 Chinese adolescents (girls were 1202, Mage = 12.75, SD = 0.58 at baseline, range = 11–16). Results indicated that parental phubbing significantly positively predicted adolescents’ reactive aggression but not proactive aggression. Self-esteem significantly predicted the adolescents’ reactive and proactive aggression. Self-esteem significantly mediated the associations between parental phubbing and adolescents’ proactive and reactive aggression, respectively. These findings suggest that intervening with parental phubbing is a promising way to reduce adolescents’ reactive aggression, and promoting adolescents’ self-esteem is an effective approach to prevent their proactive and reactive aggression.
