The Somali boubou (Laniarius erlangeri) is a species of boubou. It was split from the tropical boubou (Laniarius aethiopicus) as a result of DNA sequence analysis, and this change in status was recognized by the International Ornithological Committee in 2008. Two color morphs are recognized, a predominantly black one and an extremely rare black and yellow morph which was formerly considered a separate species, the Bulo Burti boubou (Laniarius liberatus). The Somali boubou is endemic to Somalia. The species epithet commemorates German ornithologist Baron Carlo von Erlanger who collected the holotype near Umfudu in June 1901.
