This paper reviews studies of the snakes of northeastern India published between 2001 and 2024 identified from searchable databases, covering diversity, range extension, distribution records, new genus, new species, redescription, rediscovery, and taxonomic revision. This analysis of the literature and publicly available information presents an updated checklist of 126 snake species representing 12 families and 46 genera, along with their distribution across states in northeastern India and their IUCN Red List status. The study also reveals a research gap in some northeastern states that provides opportunities for further regional studies.
