Histories of colonialism matter for research on gender-based violence (GBV) and questions of how to prevent it. This paper aims to contribute to theoretical debates on decolonizing GBV research by reflecting on the challenge of doing so as part of a long-term ethnographic engagement with communities in Samoa and Peru. I present three “epistemic entry-points,” which point to the potential for moving the project of decoloniality forward through increasing the diversity of what we think we know about gender and violence. This presents a radical undertaking for a field currently focused on achieving decolonization through improving leadership from the Global South.
