Yass is a town in the Southern Tablelands of New South Wales, Australia in Yass Valley Shire. 

The name appears to have been derived from an Aboriginal word, "Yarrh" (or "Yharr"), said to mean 'running water'.

Yass is located about 280 km southwest of Sydney, on the Hume Highway. The Yass River, which is a tributary of the Murrumbidgee River, flows past the town. Yass is 59 km from Canberra.
