Greenmount is a locality and a geographical feature in the Shire of Mundaring, Western Australia, on the edge of the Darling Scarp. It is a vital point in the transport routes from the Swan Coastal Plain into the hinterland of Western Australia.

Ensign Robert Dale reached the summit on 18 October 1829. John Septimus Roe communicated with Dale over the York Road he had used the name Green Mount.

In the era of the Swan River Colony the name 'Greenmount' was used for two points on the Darling Scarp. In the 1840s the York Road was known as York Greenmount, and the road further north along the Scarp was known as Toodyay Greenmount. It is possible that these two locations might have had slightly different coloured foliage compared to the grey blue green colour of the Scarp.

During the convict era, in 1854 Edward Du Cane was the supervisor of the building of a convict depot on the slopes of the hill. In the 1870s a government bluestone quarry was developed on the western slope of the hill.

Chippers Leap is a memorial stone on the northern edge of the Great Eastern Highway between the two points where the Old York Road remains linking with the highway.

Greenmount Hill, either by Old York Road, or Great Eastern Highway is the main ascent to, or descent from the Darling Scarp, and has been a regular site of vehicle breakdowns or accidents due to the slope.

Due to a large increase of heavy truck traffic using the hill, the Truck Arrester Bed located at the lower end of the hill has been in place since an accident in 1993.

On its western slopes and southern slopes the original Eastern Railway route travelled. On its western slopes and just to the north the later National Park deviation ran. The current railway route still passes within a few kilometres to the west and north of the hill. Greenmount was a railway stopping place until 1954 when the Mundaring Loop was closed for passenger traffic, however trains continued to work on the line to the Mountain Quarry in Boya until 1962.
