Jimmy Clements

Jimmy Clements ( – 28 August 1927) was an Aboriginal elder from the Wiradjuri tribe in Australia, and was present at the opening of the Provisional Parliament House in Canberra on 9 May 1927. He explained that he was there to demonstrate his "sovereign rights to the Federal Territory", making this the first recorded instance of Aboriginal protest at the Parliament.

He was also known as "King Billy" and also as Nangar or Yangar.

Clements and another Wiradjuri man, George Noble, had walked for nearly a week over the mountains from Brungle Mission near Gundagai, New South Wales. The two men were the only Indigenous people to attend the first opening of parliament. Clements was initially told to move on by police at the ceremony due to his attire but due to popular support from other members of the crowd he was among prominent citizens who were presented to the Duke and Duchess of York.
