The etiopathological explanations of psychiatric disorders shifted from the biological to the biopsychosocial model. However, social determinants of psychiatric disorders have been poorly researched in South Asian countries like Bangladesh. Social psychiatry is yet to be developed as a separate entity with a lack of specialized degrees and training. In the current chapter, we discuss various aspects of social psychiatry in Bangladesh like social epidemiology of mental illness, mental health literacy and stigma toward mental health, health-seeking behavior, community attitude toward mental health, disorders and treatment, substance abuse, culture-bound syndromes, different social determinants of mental illness, mass media representation of mental illness, somatization, social prescribing, the role of traditional healing practices and their integration with modern psychiatric care, challenges and opportunities in implementing community-based mental health interventions, Mental Health Act and social rights, suicidal behavior, and prison mental health. We presented it based on available evidence from Bangladesh and to some extent our personal experience.
