The Styan's bulbul or Taiwan bulbul (Pycnonotus taivanus, Chinese: 烏頭翁) is an endemic species of bulbul that lives in eastern and southern Taiwan. Though common in some areas, it has been listed as a species vulnerable to extinction. Its decline has been caused by habitat destruction and hybridisation with the closely related Chinese or light-vented bulbul (Pycnonotus sinensis); the two species' ranges overlap in several areas, partly because birds of the latter species have been released for Buddhist ceremonies. The species has already become extinct in Yilan County.

The Styan's bulbul has a very similar appearance to the light-vented bulbul, but they differ in the patterns on the head. The Styan's bulbul has a completely black crown with white feathers around its eye, except for a black moustachial stripe below the beak. Hybrids are intermediate between the two species, with the moustachial stripe and white feathers around the eye, but the white feathers extend behind the crown.
