Kunzea baxteri is a shrub in the family Myrtaceae. It is endemic to the south-west of Western Australia, where it occurs on granite outcrops and hills. It grows to between 1 metre (3 ft 3 in) and 4 metres (13 ft) in height. It is one of two Kunzea species that produces red flowers (the other being Kunzea pulchella). The flowers are produced between July and March in its native range. The species was first formally described by Johann Friedrich Klotzsch as Pentagonaster baxteri in 1836 in Allgemeine Gartenzeitung. The name was revised to Kunzea baxteri by Johannes Conrad Schauer in 1844.
