Introduction: This research conducted to assess the relationship between attachment to parents, moral identity, and self-esteem among female college students.
 Materials and Methods: The statistical community of this descriptive correlational study included all bachelor female college students of Tabriz University in 2010. So, 289 students of different academic courses were selected by cluster multistage sampling method. All participants were asked to complete Rosenberg Self-Esteem Scale, Inventory of Parent Attachment (IPPA), and Moral Identity Scale. In order to analyze the data, Pearson's correlation coefficient and stepwise multiple regression method and SPSS software were applied.
 Results: The results of stepwise multiple regression indicated 3 significant stages. The third stage results indicated that the attachment to parents (trust and alienation), and the internalization subscale of moral identity, predicted 13 percents of the variance related to self esteem (P<0.05, F=12.12, R²=0.12).
Conclusion: Based on the results of the present study, it can be concluded that a parental trust was the best and strongest predictor of self-esteem in female students.
