The Rosette-Nosed Chameleon (Rhampholeon spinosus) is a small East African species, found in virgin forest and woodland of both the eastern and western Usambara Mountains. It is predominantly ash-grey in colouration, with a distinctive rosette-like nasal appendage.

This species has, in the past, caused much taxonomic controversy—and has been reclassified from Chamaeleo spinosum, to Bradypodion spinosum, to the current Rhampholeon spinosus.
