Sassi's Greenbul (Phyllastrephus icterinus lorenzi) is a species of songbird in the Pycnonotidae family. It is found in Democratic Republic of the Congo and Uganda.
Originally described as a distinct species, it is usually treated as a subspecies of the Icterine Greenbul today. BirdLife International revised its status to subspecies in 2008.
Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is becoming rare due to habitat loss; when it was still considered a good species, it was classified as Near threatened by the IUCN.
