The Kikuyu mountain greenbul (Arizelocichla kikuyuensis), also known as the olive-breasted greenbul, is a species of the bulbul family of passerine birds.

It is found in eastern Democratic Republic of Congo, south-western and south-eastern Uganda, Rwanda, Burundi, and central Kenya.

[1] The Kikuyu mountain greenbul was originally described in the genus Xenocichla (a synonym for Bleda), then classified in Andropadus and, in 2010 re-classified to the new genus Arizelocichla.

The English name and the specific epithet are from the name of the Kikuyu people that live in Kenya.
