Coluber is a genus of thin-bodied, fast-moving, colubrid snakes commonly known as racers. They are widespread around the world and vary greatly in habitat and behaviour. In the past, Coluber was a catch-all genus which included almost all snake species known at the time. Even the cobra was once classified as Coluber naja.

As presented here, the genus is limited to its "modern" content of racers and whipsnakes. Still, some of these species (namely the whipsnakes) are increasingly separated as Dolichophis and others probably also do not really belong here.


The following species and subspecies may be included in the genus Coluber, sensu lato.[3]

Nota bene: In the following list, a taxon author in parentheses indicates that the species or subspecies was originally described in a genus other than Coluber.
