Eucalyptus forrestiana, commonly known as fuchsia gum, Forrest's mallee or Forrest's marlock, is a small tree which occurs in an area near Esperance in Western Australia. It was named after George Forrest (1873-1932). It is a mallee Eucalyptus with smooth bark and grows to between 1.5 and to 6 metres in height. It has bright red buds and yellow flowers which appear between summer and winter. Two closely related species, E. dolichorhyncha and E. stoatei, have been treated as subspecies in the past.
