Eucalyptus olsenii, Woila gum, is an Australian eucalypt of restricted habitat.
It is a small tree to 20 m with smooth, white bark, shedding in ribbons.
Adult leaves are stalked, lanceolate or curved and oblique, 8–12 cm long, 1.5–2 cm wide, green, glossy, and concolorous. Young leaves and stems are covered with fine hairs.
White flowers appear in spring to early summer.
Distribution is very restricted to mountains north east of Cooma in New South Wales on rough rocky terrain, but it grows well as an ornamental tree.
