Taxonomy
The orange-backed woodpecker was described and illustrated in 1825 by Dutch zoologist Coenraad Jacob Temminck in his Nouveau recueil de planches coloriées d'oiseaux from specimens that had been collected on the Indonesian island of Java. He coined the binomial name Pic validus.

Two subspecies are recognised:
 * C. v. xanthopygius (Finsch, 1905) – the Malay Peninsula, Sumatra, and Borneo
 * C. v. validus (Temminck, 1825) – Java
