Wetlands are among the most vital ecosystems, crucial for biodiversity, ecological balance, and local livelihoods. Human interactions threaten their sustainability, making stakeholder identification and understanding essential for conservation. This study aims to identify and prioritize key stakeholders influencing the Miankaleh Wetland. Data were collected via Delphi questionnaires and expert opinions. The Entropy method was used to assign weights to indicators, while TOPSIS and ARAS multi-criteria decision-making models ranked stakeholders. Results showed that future generations were prioritized highest, with weights of 0.7948 (TOPSIS) and 8.15 (ARAS). Non-governmental organizations and the Department of Environment followed, with weights of 0.7257 and 6.150, respectively. The findings underscore the importance of forward-thinking management that emphasizes education and public participation. Ultimately, this research provides a scientific foundation for the effective, sustainable, and intelligent conservation of the Miankaleh Wetland.
