This study was aimed at investigating the gender differences in the relationships among parental attachment, educational gender egalitarianism, and achievement motivation in university students in Korea. A total of 338 students from the Seoul and Kyungnam areas participated in this study. The results found that male students showed lower levels of mother attachment and educational egalitarianism and higher levels of achievement motivation compared to female students. For female students, parental attachment and educational egalitarianism were significantly correlated with achievement motivation; however, no such relationships were detected in male students. For male students, social and demographic variables were more predictive of achievement motivation than attachment or educational egalitarianism.
