This study examined the role of university students’ gaming addictions and online gaming motivations in predicting their online prosocial behaviors. The data collection instruments used in the study were the Personal Information Form, Online Prosocial Behavior Scale for University Students, Motives for Online Gaming Questionnaire, and Digital Game Addiction Scale for University Students. A total of 452 undergraduate students participated in the study. According to the multiple linear regression analysis results, the model variables explained 11% of the variance in online prosocial behavior. However, gaming addiction and coping/escapism, fun, fantasy, and competition motivations were not significant predictors of online prosocial behaviors. The findings were discussed, and recommendations were presented.
