This chapter aims to disseminate theoretical and practical knowledge of practice using an empowerment and feminist perspective specifically when working with marginalized and oppressed forensic populations and in forensic settings. Forensic social work focuses on both victims and offenders, and strives to integrate the skills and knowledge of empowerment and feminist theory and practice with principles of social justice and human rights. The chapter discusses empowerment and feminist theories and their relevance to practice with forensic populations. It highlights a case example of group work with women, who were sexually abused, that was first presented in the 1990s and told from a strengths-based approach, but could very much be considered both a feminist and empowerment process of working. The chapter also highlights applying an empowerment approach to working with female and male prisoners in London.
