The white-throated greenbul (Phyllastrephus albigularis) or white-throated bulbul, is a species of passerine bird in the bulbul family, Pycnonotidae.

The white-throated greenbul was formally described and illustrated in 1882 by the English ornithologist Richard Bowdler Sharpe based on a specimen collected in the Fantee region of central Ghana.

[2][3] It is now one of 21 species placed in the genus Phyllastrephus that was introduced in 1832 by the English naturalist William Swainson.

[5] The specific epithet albigularis combines Latin albus meaning "white" with Modern Latin gularis meaning "throated".

The white-throated greenbul is now monophyletic: no subspecies are recognised.
