Eucalyptus grossa, also known as Coarse-leaved Mallee , is a species of Eucalyptus which is endemic to Western Australia. Other common names for this species include the Coarse-flowered Mallee and Phillip River Gum.


Eucalyptus grossa is a mallee which grows from 0.5 to 5 metres high. It has rough, grey bark, smooth, reddish branchlets and large, thick leaves. The flower buds are bullet-shaped which are red-brown in colour and are attached to a thick, rounded, peduncle. Flowering occurs from late winter to late spring (August to November in Australia). The flowers are large and yellow or green in colour.


The species occurs in an area around Esperance on rocky plains.


The species was first formally described by botanist George Bentham in 1867.
