The common wallaroo (Osphranter robustus), also known as the euro, hill wallaroo, or simply wallaroo is a species of macropod. The word euro is particularly applied to one subspecies (O. r. erubescens).

the euro or western wallaroo (O. r. erubescens) – found covering most of the species' remaining range to the west; this subspecies is variable, but mostly brownish, in colour.

The Euro is the arid-zone sub-species of the most widespread kangaroo, the Common Wallaroo (or Hill Kangaroo). Euros have a large naked rhinarium giving them a dark shiny ‘button nose’ like koalas and wombats. They have no facial stripe but they do have large rounded ears. Their coat is coarser and shaggier than the fine down of Red Kangaroos. Females are relatively short and small and rarely exceed 25 kg. Their coat colour varies from light grey through light tan to dark grey. Males are short but very stocky with pronounced forearm musculature when mature. They reach around 50 kg and show a similar variation in coat colour to females but are distinguished by a rufous-brown nape and may often be darker coloured than females. The underparts are lighter and the tail tip is not black.

Euros hop on their short legs in an upright posture, which seems less elegant than Red and Grey Kangaroos on flat ground, but comes to the fore as they effortlessly bound up rocky slopes. The Euro is a hill-dweller and so occupies the slopes and ridges, using rocky overhangs and shallow caves as shelter in summer. Males sometimes follow more densely vegetated drainage channels out onto the plains in drought. Thus Euros are most common on the hills of various highly eroded ranges across arid and semi-arid rangelands. In some places they inhabit low lying areas of dense scrub. Females tend to be more easily alarmed by people than males who sometimes tolerate quite close approach.
