瀕危物種(英語:endangered species)是一種保護狀況,是指物種由於濫捕、盜獵、環境破壞、數量稀少、棲地狹窄等種種原因而導致其野生種群在不久的將來面臨絕滅的機率很高。一個關鍵物種的滅絕可能破壞當地的食物鏈,造成生態系的不穩定,並可能最終導致整個生態系統的崩解。

瀕危動物有:菲律賓果蝠、黑猩猩、琉球兔、藍鯨、大熊貓、小熊貓、虎、雪豹、亞洲象、水牛、台灣鮭魚 等

An endangered species is a species of organisms that will likely become extinct. The phrase 'endangered species' colloquially refers to any species that fits this description whereas conservation biologists typically use it to refer to species that are designated Endangered in the IUCN Red List, wherein "endangered" is the second most severe conservation status for wild populations, following Critically Endangered. 3079 animals and 2655 plants are Endangered worldwide, compared with 1998 levels of 1102 and 1197, respectively.[1] The amount, population trend, and conservation status of each species can be found in the Lists of organisms by population.

Many nations have laws that protect conservation reliant species: for example, forbidding hunting, restricting land development, or creating preserves.
