Psammomys is a genus of rodents in the family Muridae.[1]

The etymology of the genus name derives from the two ancient greek words ψάμμος (psámmos), meaning "sand", and μῦς (mûs), meaning "mouse, rat".[2][3]

The complete nuclear DNA genome of one Psamomys species, P. obesus, has been sequenced in 2017.[4]

It contains the following species:
