Eucalyptus lacrimans, commonly known as weeping snow gum,[2] is a species of small tree that is endemic to New South Wales.

It has smooth white bark, lance-shaped adult leaves with more or less parallel veins, flower buds in groups of seven to eleven or more, white flowers and cup-shaped, conical or barrel-shaped fruit.Eucalyptus lacrimans is a tree that typically grows to a height of 12–15 m (39–49 ft) and forms a lignotuber.

[2][3][4] Eucalyptus lacrimans was first formally described in 1991 by Laawrie Johnson and Ken Hill from a specimen collected on the Long Plain in 1984 and the description was published in the journal Telopea.

[4][5] The specific epithet (lacrimans) is a Latin word meaning 'weeping', in reference to the distinctive weeping branches of this species.

[4] The weeping snow gum grows on more or less flat, treeless plains in subalpine areas near Adaminaby, Kiandra and Rules Point in southern New South Wales.
