Tasmanian oak refers to the hardwood produced by several Eucalyptus (Gum) species native to Tasmania: Eucalyptus regnans, Eucalyptus obliqua, Eucalyptus delegatensis or Eucalyptus globulus when it is sourced from the Australian state of Tasmania. The hardwood timber is light-coloured, ranging from straw to light reddish brown. It is used in construction, including panelling and flooring, for furniture, and for reconstituted board and high quality paper. When sourced from Victoria, the wood of Eucalyptus regnans and Eucalyptus delegatensis is called Victorian ash. The species are also widely known by their common names. Eucalyptus obliqua is known as stringybark or messmate, Eucalyptus regnans is known as mountain ash, the closely related Eucalyptus delegatensis is known as alpine ash or woollybutt, and Eucalyptus globulus is known as Tasmanian bluegum, southern blue-gum or blue gum.
