Eucalyptus gigantangion is a tree that typically grows to a height of and forms a lignotuber. It has rough but soft, fibrous, orange-brown to red-brown, dark grey or black bark over most of the trunk with the upper trunk and branches covered with smooth white bark. Young plants and coppice regrowth have broadly lance-shaped to egg-shaped leaves that are long and wide. Adult leaves are arranged alternately, dull green to blue-green but lighter on one side, narrow lance-shaped, long and wide, the base tapering to a petiole long.The flower buds are arranged in groups of seven on a peduncle long, the individual buds more or less sessile. Mature buds are spindle-shaped, long and wide with ribs on the sides, four small teeth at the tip, and a conical operculum. Flowering occurs from July to August and the flowers are orange. The fruit is a woody urn-shaped capsule long and wide with ribs on the sides and the valve enclosed below rim level.
