Gwoya Tjungurrayi, also spelt Gwoja Tjungarrayi, Gwoya Jungarai, and Gwoya Djungarai, and also known by his nickname One Pound Jimmy, is known for being the first Aboriginal person to be featured on an Australian postage stamp, in 1950, although his name was not used to describe the image on the stamp. A survivor of the 1928 Coniston massacre in the Northern Territory, he later became an elder and lawman of his people. The name Gwoya, is a non-Indigenous rendering of the Anmatyerr word 'Kwatye', meaning 'water' or 'rain'.

The Coniston massacre, which took place in the region around the Coniston cattle station in the territory of Central Australia from 14 August to 18 October 1928, was the last known officially sanctioned massacre of Indigenous Australians and one of the last events of the Australian frontier wars.
