The IUCN National Red List Working Group (NRLWG) is a working group within the IUCN expert Commissions focussed on developing and implementing ways to improve linkages between national red listing efforts and the IUCN Red List, and on tools to help national red listing efforts, which are often based on adapting the tools available for global red listing processes to better suit national needs.

The NRLWG are custodians of the National Red List Project and are actively involved in advising and guiding the redevelopment process for the database and website.
