Eucalyptus robusta, commonly known as swamp mahogany or swamp messmate, is a tree native to eastern Australia.
Growing in swampy or waterlogged soils, it is up to 30 m (98 ft) high with thick spongy reddish brown bark and dark green broad leaves, which help form a dense canopy. The white to cream flowers appear in autumn and winter.
The leaves are commonly eaten by insects, and are a food item for the koala. It is an important winter-flowering species in eastern Australia, and has been planted extensively in many countries around the world. Its timber is used for firewood and in general construction.
