This study aims to enrich the growing literature on Islamic feminism in Indonesia by exploring its intersection with digital activism. Contextualized within Indonesia's sociopolitical history, including the rise of Islamic conservatism post-Suharto, it highlights the challenges and opportunities of integrating religious and feminist values to combat gender-based violence (GBV) and foster inclusive discourse. Focusing on Mubadalah—a framework of gender reciprocity, an Islamic feminist movement, and a method of interpreting Islamic texts—the research examines how its activists address GBV perpetuated by patriarchal interpretations of Islam. A significant focus is on GBV in religious institutions, particularly pesantren (Islamic boarding schools). Findings reveal Mubadalah’s digital strategies, which include leveraging ulema endorsements, utilizing trending media narratives and social media algorithms for advocacy, and rehabilitating the image of pesantren by promoting “positive pesantren”. These approaches demonstrate the potential of digital activism to reshape discourse and challenge gender inequalities in Indonesia.
