Tintinara is a town located in the Murray Mallee region of South Australia.
The town is situated on Dukes Highway and the Adelaide-Melbourne railway line. It is in The Coorong District Council local government area, the South Australian House of Assembly Electoral district of MacKillop and the Australian House of Representatives Division of Barker. At the 2006 census, Tintinara had a population of 257.
The origin of the name has been debated. One possibility is that a local Aborigine in the area was named Tin-Tin, and the 'ara' was appended to form the placename; or that the Aborigine, one of the Boothbys' employees, was named Tintinara. It has also been suggested that the name may have been a corruption of an Aboriginal word, tinlinyara, which is the word for the stars in Orion's belt.
