This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.

In actual theoretical practice, a species not definitely located in the wild in the last 50 years of current time is textually called "extinct".
