瀕危物種係指一個物種，由於濫捕、盜獵、環境破壞、數量稀少、棲地狹窄等種種原因導致有滅絕危機嘅物種。根據 IUCN(國際自然保護聯盟)嘅標準，瀕危物種名單會依據物種具體狀況而修訂，因此這是一個在變化中的列表。
Endangered species refers to a species that is in danger of extinction due to various reasons such as overfishing, poaching, environmental damage, scarcity of numbers, and narrow habitats. According to IUCN (International Union for Conservation of Nature) standards, the list of threatened species is revised according to the specific status of the species, so this is a changing list.
