Ruby Tjangawa Williamson (c. 1940 – September 2014) was a Pitjantjatjara artist from Amaṯa, in central Australia.
She made acrylic paintings and traditional wood carvings, and was one of the most successful artists from the region.
Williamson painted sacred stories from the Dreamtime that have morals or lessons from her people's traditional law.
Her family spent most of their time travelling between her father's homeland near Pukara and her mother's around Mantamaru.
[2] Her artwork has been shown alongside works by other Tjala artists in every major city in Australia.
