Dargo is a town in Victoria, Australia, located 348 km east of Melbourne, in the Shire of Wellington. At the 2016 census, Dargo and the surrounding area had a population of 99. The median age of residents was 63. The town provided a stopover for Victorian Gold Rush miners on their way to the goldfields of Grant, Talbotville, and Crooked River. The Post Office opened on 18 March 1868. Today the town is a producer of timber and beef cattle, and outside these industries tourism has become a major source of revenue. The town is a popular destination for four-wheel drive enthusiasts, bushwalkers, sambar deer hunters, and trout fishermen. An annual Walnut Festival formerly ran through the Australian Easter holiday period and was usually well attended.
