The You Yangs are a series of granite ridges that rise to 319m (Flinders Peak) above the Werribee Plain approximately 55 km south-west of Melbourne and 22 km north-east of Geelong, in Victoria, Australia. The main ridge runs roughly north–south for about 9 km, with a lower extension running for about 15 km to the west. Much of the southern parts of the ranges are protected by the You Yangs Regional Park.
Although only 319 m at their highest, they dominate the landscape and are clearly identifiable from nearby Geelong, Melbourne and beyond. Camping is not permitted in the You Yangs. The foothills to the north of the peaks are home to Ford Australia's proving ground.
The You Yangs are also the home of a Geoglyph constructed by the Australian artist Andrew Rogers in recognition of the indigenous people of the area. It depicts Bunjil, a mythical creature to the local Wathaurong Aboriginals. This geoglyph has a wing span of 100 metres and 1500 tonnes of rock was used to construct it, and was unveiled in March 2006.
