List of extinct animals of the British Isles

This is a list of extinct animals of the British Isles, including extirpated species. Only a small number of the listed species are globally extinct (most famously the Irish elk, great auk and woolly mammoth). Most of the remainder survive to some extent outside the islands. The list includes introduced species only in cases where they were able to form self-sustaining colonies for a time. Only Pleistocene species, and specifically those extinct since the Ipswichian/Eemian interglacial (c. 130,000 - c. 115,000 before present (BP)), Devensian glaciation (c. 115,000 – c. 11,700 BP) or into the Holocene (c. 11,700 BP - present), are included (that is, the assemblage that can be approximately considered the 'modern' fauna which displays insular differences from the mainland European fauna). The date beside each species is the last date when a specimen was observed in the wild or, where this is not known, the approximate date of extinction.
