The yellow-bellied bulbul (Alophoixus phaeocephalus) is a species of songbird in the bulbul family, Pycnonotidae.

It is found on the Malay Peninsula, Sumatra and Borneo.

Its natural habitat is subtropical or tropical moist lowland forests.

The yellow-bellied bulbul was originally described in the genus Ixos and alternatively classified in the now defunct genus Trichixos.

The alternate name 'grey-headed bulbul' should not be confused with the species of the same name, Pycnonotus priocephalus.
