The frosted hairy dwarf porcupine (Coendou pruinosus) is a porcupine species in the family Erethizontidae{{MSW3 Hystricognathi | id = 13400124 | page = 1549}} from Colombia and northern and eastern Venezuela. It was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic.{{cite journal|last1= Voss|first1=R.
