Glires (/ˈɡlaɪəriːz, -aɪərz/[citation needed], Latin glīrēs 'dormice') is a clade (sometimes ranked as a grandorder) consisting of rodents and lagomorphs (rabbits, hares, and pikas).

The hypothesis that these form a monophyletic group has been long debated based on morphological evidence.

In particular, the 2003 study reported the discovery of fossil material of basal members of Glires, particularly the genera Mimotona, Gomphos, Heomys, Matutinia, Rhombomylus, and Sinomylus.

[6] A study, published in 2007,[7] investigating retrotransposon presence/absence data unambiguously supports the Glires hypothesis.
