The Latjilatji were an indigenous Australian people of the state of Victoria, Australia.
The ethnonym Latjilatji consists of a reduplication of the word for 'no' (latja)
Latjilatji was a Western Central Murray language classified as a member of the Kulinic language branch of the Pama Nyungan language family. It was closely related to Matimati and Wadiwadi. A vocabulary of the tongue, compiled by E. M. Curr from informants interviewed at Kulkyne, was published in 1887.
The Latjilatji lands extended over some 3,500 square miles (9,100 km2), ranging from Chalka Creek to Mildura on southern bank of Murray River, and stretching some 50 miles to its south. It encompassed Kulkyne, and ran south as far the vicinity of Murrayville and Pine Plains.
The Latjilatji were divided into two moieties, the Kailpara and Makwara, the former connected to the emu, the latter to the eagle-hawk. A child's descent was traced through the mother.
The early explorer Edward Eyre mentioned them in his work (1845)under the name Boraipar and transcribed a number of words from their language. The smallpox that devastated the Latjilatji, as it did all the Murray riverine tribes (Tatitati, Jitajita, Nari-Nari, Barapa Barapa, Warkawarka, Watiwati, Wemba-Wemba) after initial contact with whites was established, was described by Peter Beveridge, writing of his impressions in the 1850s.
