'Eucalyptus deglupta' is a species of tall tree, commonly known as the rainbow eucalyptus, Mindanao gum, or rainbow gum that is native to the Philippines, Indonesia, and Papua New Guinea. It usually lives in rainforest, with a natural range that extends into the northern hemisphere. It is characterized by multi-colored bark.

'Eucalyptus deglupta' is a fast-growing tree that typically reaches a height of 60–75 m (197–246 ft) with the trunk up to 240 cm (94 in) in diameter and with buttresses up to 4 m (13 ft) high. It has smooth, orange-tinted bark that sheds in strips, revealing streaks of pale green, red, orange, grey, and purplish brown. Flowering time depends on location, and the stamens that give the flowers their colour are white and pale yellow. The fruit is a woody, brown, hemispherical capsule. Each cell of the fruit contains between three and twelve minute brown seeds, each with a small wing.

This tree is grown widely around the world in tree plantations, mainly for pulpwood used in making white paper. It is the dominant species used for pulpwood plantations in the Philippines.
