A mallet is a small-tree form of Eucalyptus found in Western Australia. Unlike the mallee, it is single-stemmed and lacks a lignotuber. Species of this form have a relatively long, slender trunk, steeply-angled branches, often a conspicuously dense terminal crown, and sometimes form thickets.

Mallet species include:

• Brown mallet (Eucalyptus astringens)
• Blue mallet, blue-leaved mallet, Gardner's mallet (Eucalyptus gardneri)
• Green mallet (Eucalyptus clivicola)
• Salt River mallet, Sargent's mallet (Eucalyptus sargentii)
• Silver mallet (Eucalyptus falcata or Eucalyptus ornata)
• Steedman's mallet (Eucalyptus steedmanii)
• Swamp mallet (Eucalyptus spathulata)
• White mallet (Eucalyptus falcata or Eucalyptus spathulata)
• Fuchsia gum (Eucalyptus dolichorhyncha)
