The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List), founded in 1965, has evolved to become the world's most comprehensive inventory of the global conservation status of biological species.
IUCN's rødliste over truede arter (også kendt som IUCN's rødliste eller IUCN's røde dataliste) (grundlagt i 1963) er verdens mest omfattende opgørelse over den globale bevaringsstatus for klodens biologiske arter.
