Coccyzus is a genus of cuckoos which occur in the Americas. The genus name is from Ancient Greek kokkuzo, which means to call like a common cuckoo. The genus includes the lizard cuckoos that were formerly included in the genus Saurothera.

Cuckoos are birds in the Cuculidae family, the sole taxon in the order Cuculiformes. The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals, and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae, respectively. The cuckoo order Cuculiformes is one of three that make up the Otidimorphae, the other two being the turacos and the bustards. The family Cuculidae contains 150 species, which are divided into 33 genera.
