This study conducts a Systematic Literature Review (SLR) of 30 Scopus-indexed articles published between 2016 and 2025 to examine the conceptualization and development of Islamic Social Enterprise (ISE) and Islamic Social Entrepreneurship (ISEn). The review reveals that ISE is predominantly framed as an organizational form integrating Islamic principles into governance, accountability, and social welfare structures, while ISEn emphasizes individual-driven innovation and entrepreneurial behavior aligned with sharī‘ah values. Despite their differences, both models converge in their pursuit of financial sustainability, social justice, and community empowerment. Thematic analysis identifies four recurring domains in the literature: governance, innovation, sustainability, and maqāṣid al-sharī‘ah. Governance studies highlight accountability, transparency, and stakeholder trust, while research on ISEn emphasizes digitalization, creative financing, and entrepreneurial intention. Sustainability is viewed not only in terms of economic viability but also as encompassing ethical and social commitments, with maqāṣid al-sharī‘ah providing a normative framework that guides decision-making and ensures alignment with faith-based objectives. The findings reveal that the conceptual boundaries between ISE and ISEn remain blurred but complementary, suggesting their integration offers both institutional stability and entrepreneurial dynamism. This study contributes to the academic discourse by clarifying definitions, synthesizing thematic trends, and identifying research gaps. Practically, the results offer implications for policymakers in designing supportive ecosystems, for practitioners in building hybrid models, and for academics in advancing theoretical clarity.
