Eucalyptus cupularis, commonly known as the Halls Creek ghost gum, Halls Creek white gum, is a eucalypt that is native to Western Australia and the Northern Territory. It is known by the indigenous Jaru peoples as wawulinggi.
The tree typically grows to a height of 5 to 9 metres (16 to 30 ft) and as high as 12 metres (39 ft). It has powdery white smooth bark. Adult leaves are disjunct, dull, green, thin and concolorous. The leaf blade has a narrow lanceolate to broad lanceolate shape that is basally tapered.
The tree blooms between October and November producing a simple axillary conflorescence with seven flowered umbellasters on quadrangular peduncles. Buds are ovoid or pyriform or conical with a calyptrate calyx that shed early with cream to white flowers. Fruits that form later are cylindrical or conical with a flat disc.
The range of the plant extends from the Kimberley region of Western Australia and extends into the Northern Territory where it grows on stony hills and along watercourses in skeletal soils over sandstone or granite.
