Feminist vigilante groups are activist organizations or loosely organized collectives that take direct, often extrajudicial, action to confront and address gender-based injustices like violence, harassment, and systemic discrimination. These groups typically arise in response to failures or inadequacies within formal legal systems, particularly in regions where authorities neglect or inadequately address the safety and rights of women and marginalized communities. Examples include the Gulabi Gang in India, which confronts perpetrators of domestic violence and abuse in rural areas, and Las Femicidas in Mexico, a group known for highlighting issues of femicide and systemic injustice through direct actions like graffiti and public confrontations. Such groups often fill a gap in local justice systems, providing both protection and empowerment in communities wherek institutional support is limited or absent.
