<![CDATA[The global halal tourism sector continues to expand rapidly; however, existing systematic reviews predominantly focus on macro-level global trends, leaving a critical research gap regarding how Maqashid al-Shariah-based management frameworks can be operationalized within specific archipelagic and cross-border contexts. This study addresses this gap by examining the sustainable halal tourism potential of Indonesia's Riau Islands Province through a localized Maqashid al-Shariah framework. Adopting a Systematic Literature Review (SLR) methodology guided by PRISMA 2020 protocols across Scopus and Web of Science databases for the 2015-2025 period, 75 eligible peer-reviewed articles were synthesized from an initial pool of 152 records using thematic content analysis and bibliometric co-occurrence mapping via VOSviewer. The bibliometric analysis identified four distinct thematic clusters: (1) Halal Supply Chain Regulatory Compliance, (2) Smart Digital Halal Tourism, (3) Sustainable Destination Management, and (4) Islamic Governance Maqashid Frameworks. Bridging these clusters, the study operationalizes six Maqashid dimensions integrating al-bī'ah (environmental stewardship) alongside the classical five dimensions (al-dīn, al-nafs, al-‘aql, al-nasl, al-māl) through contemporary Islamic eco-theological justification. Tailored to the archipelagic geometry and Malay-Islamic heritage of the Riau Islands, specific strategies are formulated, including cross-border certification harmonization, eco-resort stewardship, digital heritage preservation on Penyengat Island, and local SME empowerment through sharia microfinance. The study demonstrates that sustainable halal tourism requires shifting from mere ritual compliance toward integrated digital governance and marine ecosystem protection. The proposed framework offers actionable policy insights for regional authorities and a scalable governance model for island tourism destinations in the Global South.]]>
