Diatomyidae is a family of hystricomorph rodents. It is represented by a single living species, Laonastes aenigmamus, native to Laos in Southeast Asia. Fossil species are known from the Oligocene and Miocene of Asia and eastern Europe.
== "Lazarus effect" == Before Laonastes was discovered, the family Diatomyidae was known only from fossils. The family has a nearly continuous fossil range from Early Oligocene fossils of Fallomus from the Lower Chitarwata Formation (32.5 million years ago, Bugti Member, Bugti Hills,) in Balochistan, Pakistan, to Middle/Late Miocene fossils (11 Mya) of Diatomys.
