The mountain bulbul (Ixos mcclellandii) is a songbird species in the bulbul family, Pycnonotidae. It is often placed in Hypsipetes, but seems to be closer to the type species of the genus Ixos, the Sunda bulbul. It is found in Southeast Asia and is not considered a threatened species by the IUCN. It is named after British East India Company Surgeon John McClelland.
The mountain bulbul was originally described in the genus Hypsipetes in 1840 by Thomas Horsfield. Alternate names for the mountain bulbul include the green-winged bulbul, McClelland's bulbul, McClelland's rufous-bellied bulbul, mountain streaked bulbul, and rufous-bellied bulbul. The common name, 'mountain bulbul', is also used as an alternate name for the Cameroon greenbul.
