Legitimacy remains the cornerstone of non-profit credibility, sustainability, and influence. This article synthesises theoretical, empirical, and practical perspectives on legitimacy, consolidating insights from across the field into a cohesive framework. It identifies legitimacy as a multidimensional construct—pragmatic, moral, cognitive, representational, and epistemic—while emphasising its contested and dynamic character. The synthesis integrates findings on its sources (legal, moral, epistemic, participatory), vulnerabilities (scandals, foreign influence, corporatisation, weak grassroots ties), and strategies for resilience (participatory governance, ethical culture, adaptive management, and crisis communication). Measurement challenges are addressed through methodological pluralism, acknowledging legitimacy’s perceptual and relational foundations. Looking ahead, digital transformation, populist backlash, and decolonial critique are reshaping legitimacy’s meaning and mechanisms, shifting authority from external validation toward locally grounded and digitally adaptive forms. The article concludes that legitimacy is both a condition for organisational survival and a driver of systemic change, demanding continuous negotiation, critical reflection, and innovation from scholars and practitioners alike.
