The Gadjalivia were an indigenous Australian people of Arnhem Land in the Northern Territory. They are now regarded as extinct.
Arthur Capell classified the Gadjalivia language (Gudjälavia) as a dialect of Burarra.
Norman Tindale estimated that their lands encompassed some 200 square miles (520 km2), inland to the west of the Blyth River.
Following a drastic reduction in their numbers, remnants of the tribe, surviving around the Cadell River, are said to have been assimilated into the Nagara.
