Lichenostomus is a genus of honeyeaters endemic to Australia.

The genus formerly contained twenty species but it was split after a molecular phylogenetic analysis published in 2011 showed that the genus was polyphyletic.

[2] Former members were moved to the six new genera: Nesoptilotis, Bolemoreus, Caligavis, Stomiopera, Gavicalis and Ptilotula.

[2] The genus contains two species:[3] The name Lichenostomus was introduced by the German ornithologist Jean Cabanis in 1851.

[4] The word is derived from the Greek leikhēn meaning lichen or callous and stoma meaning mouth.
