Xerochrysum (syn. Bracteantha) is a genus of flowering plants native to Australia. It was defined by Russian botanist Nikolai Tzvelev in 1990, preceding (and taking precedence over) Bracteantha which was described the following year.[1] A 2002 molecular study of the tribe Gnaphalieae has indicated the genus is probably polyphyletic, with X. bracteatum and X. viscosum quite removed from each other.[2]

There are currently 7 recognised species:[3]

The genus was formerly included in Helichrysum.
