The common koels are three species of cuckoos. They have commonly been considered conspecific under the scientific name Eudynamys scolopaceus, but are increasingly treated as separate species:
- Asian Koel, Eudynamys scolopaceus.
- Black-billed Koel, Eudynamys melanorhynchus.
- Pacific Koel, Eudynamys orientalis.
- Australian Koel, Eudynamys (orientalis) cyanocephalus.
