This chapter provides an overview of suicidal behaviours and suicide prevention strategies among minority groups, including refugees, migrants, asylum seekers, and internally displaced persons (IDPs). The chapter highlights the interplay of cultural and gender diversity in shaping suicidal behaviours and emphasizes the need for tailored interventions that address the specific challenges faced by these populations. It reviews the existing literature on the prevalence of suicide among minority groups in both high-income countries (HICs) and low- and middle-income countries (LMICs), examining the role of cultural factors, gender-based violence, and mental health issues. The chapter also discusses suicide prevention strategies in humanitarian settings, such as community engagement, gatekeeper training, cultural adaptation of interventions, and the importance of integrating mental health services into primary healthcare services. The chapter highlights evidence-based practices recommended by research, the Inter-Agency Standing Committee (IASC), and the World Health Organization (WHO). The conclusion underscores the need of a comprehensive, culturally sensitive approach and calls for further research, increased investment in mental health infrastructure, and the development of gender-sensitive strategies to reduce the burden of suicide among minority groups in humanitarian contexts.
