This study examines the role of social entrepreneurship in promoting sustainable community development, with a focus on emerging and culturally diverse regions such as Northeast India and Nagaland. Social entrepreneurship has gained global relevance as a transformative approach for addressing socio-economic and environmental challenges through innovation, community participation, and inclusive development. Drawing upon Social Innovation Theory, Sustainable Development Theory, the Triple Bottom Line approach, and the Theory of Change, the study provides an integrated conceptual framework to understand how social enterprises generate long-term social value. Based on an extensive review of national and international literature, the study identifies major themes, including the significance of social capital, stakeholder engagement, and socio-cultural factors in shaping social enterprise operations. Findings reveal steady growth in social enterprises and community development indicators, alongside persistent challenges such as limited financial access, managerial constraints, socio-cultural barriers, and inadequate policy support. The research highlights significant gaps in region-specific evidence, particularly in tribal and remote contexts, and emphasizes the need for targeted strategies, policy reforms, and capacity-building initiatives. Overall, the study contributes to the existing body of knowledge by providing a comprehensive analysis of the dynamics, challenges, and developmental impact of social entrepreneurship while outlining future research opportunities to strengthen sustainable community development..
