Despite the last few decades’ advances towards social and gender justice, reproductive decisions are still a source of oppression for many European Romani women and girls. This protocol aims to propose a model to empower Romani women and girls’ reproductive decisions, inspired by Reproductive Justice—the recognition of women and girls’ ability to make safe and free decisions about their bodies and reproduction. Through Participatory Action Research, 15–20 Romani girls and their families, two Romani platforms, and key agents from a rural and an urban context in Spain will participate. They will (1) contextualize Romani women and girls’ inequities, (2) build partnerships, (3) implement Photovoice and advocate for their gender rights, and (4) assess the initiative’s related changes, using self-evaluation techniques. Qualitative and quantitative indicators will be collected to assess impacts among participants, while tailoring and assuring the quality of the actions. Expected outcomes include the creation and consolidation of new social networks, and the promotion of Romani women and girls’ leadership. For this, Romani organizations must be transformed into empowering settings for their communities, spaces where Romani women and girls assume responsibility of the initiatives, being these tailored to their real needs and interests, and guaranteeing transformative social changes.
