The black-crested bulbul (Rubigula flaviventris) is a member of the bulbul family of passerine birds. It is found from the Indian subcontinent to southeast Asia.
The black-crested bulbul was originally described in the genus Vanga and later moved to genus Pycnonotus. Pycnonotus was found to be polyphyletic in recent molecular phylogenetic studies and five bulbul species, including the black-crested bulbul, moved to Rubigula.
Until 2008, the black-crested bulbul was considered as conspecific with the black-capped, ruby-throated, flame-throated and Bornean bulbuls.
