Tanbar County, Queensland is a cadastral division of Queensland and a County of the South Gregory District of far western Queensland. The county came into existence on 8 March 1901, when the Governor of Queensland issued a proclamation legally dividing Queensland into counties under the Land Act 1897.Like all counties in Queensland, it is a non-functional administrative unit, that is used mainly for the purpose of registering land titles. From 30 November 2015, the government no longer referenced counties and parishes in land information systems however the Museum of Lands, Mapping and Surveying retains a record for historical purposes.
