Objectives: Depending on different circumstances, religious variables may reduce or stimulate pathological attitudes towards death. The present study was carried out with the aim of investigating the relationships between death obsession, religious coping, acting on religious beliefs and attachment to God. Method: In a correlational study, a sample of 300 participants was selected using stratified sampling method.  Participants responded to Death Obsession, Acting on Religious Beliefs, Religious coping, and Attachment to God Scales. Data were analyzed using stepwise multiple regression analysis. Results: Among religious variables, insecure attachment to God and negative religious coping had greater contribution in predicting death obsession. Conclusion: Those whose beliefs about God are a source of punishment rather than love, and those who are doubtful and anxious in accepting God as a secure base may experience more death obsession.
