Background/Objectives: Although parental mediation has been widely recognized as a protective factor against cyberbullying, evidence regarding restrictive mediation remains inconsistent and sometimes contradictory. This inconsistency underscores the need to identify potential moderators. The present study examines whether parent–child relationship qualities (trust and alienation) and child gender moderate the associations between restrictive mediation and both cyber-aggression and cyber-victimization. Methods: Participants included 2075 adolescents (Mage = 16.50, SD = 3.11; 926 boys) from Grades 7–12 in urban China. Self-report measures assessed restrictive mediation, parent–child trust and alienation, and adolescents’ involvement in cyber-aggression and cyber-victimization. Results: Parental restrictive mediation and parent–child alienation were positively associated with adolescents’ cyber-aggression and cyber-victimization, whereas parent–child trust was negatively associated with both outcomes. Moreover, parent–child alienation significantly moderated the associations between parental restrictive mediation and cyberbullying, such that restrictive mediation predicted higher levels of cyber-aggression and cyber-victimization under conditions of greater alienation. These moderating effects were particularly pronounced among boys, whereas for girls, the association was weaker or non-significant. Conclusions: These findings suggest that inconsistencies in prior research may be explained by variations in parent–child alienation and gender. The results highlight the need to foster trust and reduce alienation in parent–child relationships, rather than relying solely on restrictive Internet control, to prevent adolescents’ involvement in cyberbullying.
