(The) Putty Road is a 168-kilometre (104 mi)-long[1] rural road that links the Hunter Region in New South Wales to Wilberforce, just north of Windsor on the far northwestern suburban edge of Sydney, Australia.

[4] Putty Road commences as John Street in Singleton, running in a southerly direction as a two-lane, single carriageway road, crossing the Main Northern railway line as Putty Road and continuing south until the intersection with Mitchells Line of Road (part of Golden Highway); Putty Road and Golden Highway are concurrent for around 2 kilometres through the Mount Thorley industrial estate, before Putty Road branches south-east to run through Bulga, Milbrodale, Putty and Colo, bounded to the west and east by protected national parks – the Wollemi National Park to the west, and the Yengo National Park to the east – both part of the UNESCO World Heritage-listed Greater Blue Mountains Area.

It was opened in 1823 and was initially a popular cattle-duffing (an Australian term for cattle-rustling) route.

[2] The road is narrow and winding in places and very scenic, but may be hazardous during wet weather.

[8] Its northern end was truncated to the intersection with Golden Highway at Mount Thorley on 22 November 1996; the western end of Main Road 128 was extended to cover its former alignment from Mount Thorley into Singleton (and continuing eastwards to East Gresford).
