George Jiří Chaloupka OAM, FAHA (6 September 1932 – 18 October 2011) was an expert on Indigenous Australian rock art. He identified and documented thousands of rock art sites, and was a passionate advocate for Aboriginal Australian art, as longest continuing art tradition in the world. He is especially known for the much-debated assignation of a four-phase style sequence to rock art in Arnhem Land, and the term "Dynamic Figures", which he assigned to rock art described by him in Mirrar country of western Arnhem Land.
