Nauclerus was a genus of birds of prey, containing the African and American swallow-tailed kites. Though similar, the two species are not closely related, belonging to separate subfamilies Elaninae and Perninae.
The term is preserved in the modern French common names "élanion naucler" and "naucler à queue fourchue".
