Indonesia is a global hotspot for shark and ray diversity, spanning marine and freshwater ecosystems with unique and threatened species. This study presents the first annotated checklist and conservation priority database for 176 taxa, including 15 endemics. Taxa were categorized into 13 conservation priority levels using a modified High Conservation Value (HCV 1) framework, incorporating IUCN (International Union for Conservation of Nature) status, CITES (Convention on International Trade in Endangered Species) appendices, endemicity, and legal protections, revealing one Extinct, 25 Critically Endangered, 54 Endangered, and 47 Vulnerable species, with 33 listed under CITES. Most taxa (60.8%) fall into medium priority levels, highlighting widespread but uneven threats. Endemic species, though fewer, are entirely dependent on Indonesian conservation. This checklist provides a foundation for prioritizing actions, strengthening policies, and supporting future research to protect sharks and rays crucial to ecosystems and biodiversity. © Published under licence by IOP Publishing Ltd.
