Calothorax is a genus of birds in the hummingbird family Trochilidae.
The genus Calothorax was introduced in 1840 by the English zoologist George Robert Gray with the lucifer sheartail as the type species. The name combines the Ancient Greek kalos meaning "beautiful" with thōrax meaning "breast".
A 2014 molecular phylogenetic study by Jimmy McGuire and collaborators found that the genus Calothorax was sister to the genus Doricha.
The genus contains two species:
| Male | Female | Common name | Scientific name | Distribution |
|---|---|---|---|---|
| Lucifer sheartail | Calothorax lucifer | |||
| Beautiful sheartail | Calothorax pulcher | |||
