The increasing number of forcibly displaced and traumatized migrants worldwide presents substantial ethical, clinical, and structural challenges for mental health care systems. This paper examines key ethical principles—beneficence, non-maleficence, justice, and confidentiality—in the provision of mental health care for traumatized migrants, grounded in international ethical guidelines and human rights frameworks. It emphasizes the importance of trauma-informed, culturally sensitive, and structurally aware approaches to care, particularly in contexts characterized by displacement and vulnerability. Special attention is given to the risk of re-traumatization resulting from repeated recounting of traumatic experiences across legal, humanitarian, and clinical settings, highlighting the need for careful pacing, safety, and stabilization prior to trauma-focused interventions. This chapter further addresses the essential role of interpreters, noting the ethical challenges related to confidentiality, neutrality, emotional burden, and cultural mediation. Integrated care models combining mental health services with social and legal support have been identified as critical for meeting the complex needs of displaced populations. Finally, the paper examines how migration policies, political narratives, and structural barriers influence access to mental health care, underscoring that inadequate provision constitutes not only a clinical failure but also a human rights concern. The findings highlight the need for specialized training, institutional commitment, and rights-based approaches to ensure equitable care for traumatized migrants.
