Yvonne Koolmatrie (born 1944) is an Australian artist and weaver of the Ngarrindjeri people, working in South Australia.
Her father was a Kokatha man, Joseph Roberts, and her mother Margaret was a Ngarrindjeri / Ramindjeri woman from the Coorong.
Their coiled bundle technique uses local spiny-headed sedge (Cyperus gymnocaulos), known to the artist as bilbili and river rushes,[2] and Koolmatrie is credited with saving the traditional Ngarrindjeri craft.
