List of extinct rodents

This list of extinct rodents lists the prehistoric rodents from the fossil record that are extinct−no longer extant.

The list may include extinct rodents of any period up to the ongoing Holocene −Anthropocene extinction event of the present Holocene epoch, that began approximately 11,700 years before present.

Fossils from related groups such as Lagomorpha (rabbits and hares) should not be included here.
