<p dir="ltr">Nursing, deeply rooted in social justice principles, faces the contemporary imperative of achieving health equity. However, the perception of social justice among nurses, particularly newly graduated registered nurses (NGRNs), remains unclear, posing a significant challenge amid high turnover rates in this population, threatening the realization of health equity goals.</p><p dir="ltr">Through this study, I sought to enhance nursing knowledge by delving into the understanding, cocreation, processing, and response to social justice among NGRNs. Utilizing a constructivist grounded theory methodology, I explore NGRNs’ narratives and perceptions concerning social justice, addressing the research question: How do NGRNs understand, cocreate, process, and respond to social justice in their nursing practice?</p><p dir="ltr">Findings from the grounded theory study reveal seven categories with subsequent subcategories, culminating in the development of a proposed theoretical framework. This framework elucidates four overarching global themes: “Best Care for all, No Matter What,” “Novice Emancipators,” “Making the Human Connection,” and “Supportive Organizational Culture.” I used theoretical modeling to delineate a middle-range theory titled “NGRN Evolving Process of Social Justice Transition.”</p><p dir="ltr">The study’s conclusions have significant implications for nursing education, practice, research, and policy. They highlight the importance of shaping future nursing landscapes through a focus on NGRNs’ social justice transition. Emphasizing the pivotal role of social justice identity in NGRNs’ progression to expert nurses, the study underscores the critical need to foster this identity during NGRNs’ transition period. Implications extend to curriculum structure, onboarding programs, leadership, and policy, aiming to promote person-centered care and health equity. This study marks the inception of a journey towards continual support for NGRNs as advocates for social justice, potentially catalyzing substantial societal change with nursing at the forefront of the pursuit of equity.</p>
