Eucalyptus delegatensis, commonly known as Alpine Ash, Mountain Ash, Gum-topped Stringybark or White Top, is native to south east Australia’s mountainous regions. E. delegatensis is synonymous with Eucalyptus gigantea.

The etymological root of the binomial name Eucalyptus is derived from the Greek eu ‘good‘ and kalyptos ’covered’ referring to the calyx which forms a lid over the flowers when in bud. Delegatensis is derived from the Latin meaning ‘from Delegate, New South Wales’.
