The black-tailed hairy dwarf porcupine (Coendou melanurus) is a porcupine species from the family Erethizontidae.

[2] It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Suriname and Venezuela.

This species was formerly sometimes assigned to Sphiggurus,[2] a genus no longer recognized since genetic studies showed it to be polyphyletic.

[3] Its closest relatives are the frosted hairy dwarf porcupine (Coendou pruinosus), the brown hairy dwarf porcupine (Coendou vestitus) and the streaked dwarf porcupine (Coendou ichillus).
