Nauclerus is an obsolete genus of birds of prey, containing the swallow-tailed and scissor-tailed kites. Though similar, the two species are not closely related, belonging to separate subfamilies, namely Perninae and Elaninae, respectively.

The term is preserved in the modern French common names "élanion naucler" and "naucler à queue fourchue".
