Windradyne was an Aboriginal warrior and resistance leader of the Wiradjuri nation, in what is now central-western New South Wales, Australia; he was also known to the British settlers as Saturday. Windradyne led his people in the Bathurst War, a frontier war between his clan and British settlers.

The Bathurst War (1824) was a war between the Wiradjuri nation and the United Kingdom of Great Britain and Ireland. Following the successful Blaxland, Lawson, and Wentworth expedition to find a route through the "impenetrable" Blue Mountains in 1813, this allowed the colony to expand onto the vast fertile plains of the west.
