The Fiji Bush-warbler (Cettia ruficapilla) is a species of Old World warbler in the Sylviidae family. It is endemic to the islands of Fiji. There are four subspecies occurring on all the main islands of the group. The species has been afforded its own genus, Vitia, in the past, but similarities of egg colour, song and morphology place it firmly within the Cettia bush-warblers.
