Narbethong is a town in central Victoria, Australia. It is located on the Maroondah Highway, 87 kilometres (54 mi) north east of the state capital, Melbourne. At the 2011 census, Narbethong and the surrounding area had a population of 474.
The first European settlement at Narbethong was established in about 1865 by Frederick Fisher. Fisher built a 12-room hotel, the Black Spur Inn, on the road which was being built to link Melbourne with the new goldfield at Woods Point. Fisher came from the town of Narberth in Wales, so it is likely that the name Narbethong was based on that. However, there are also claims that Narbethong is an Aboriginal word meaning cheerful, or cheerful place.
Narbethong Post Office opened on 16 October 1883 in a small room at the hotel. In about 1886 the post office moved from the hotel into a small building. The telegraph service was connected to Narbethong in 1891, with the wires being strung along fences and attached to trees. In 1939 the post office building, which was then part of a store and petrol station, was completely destroyed in the Black Friday bushfires. The Post Office closed in 1993.
A primary school opened in Narbethong on 7 July 1903. It originally was part-time, sharing a teacher with Marysville and Buxton. In 1913, the Healesville Shire health officer reported that a lack of ventilation made the building a health hazard for students and teachers. A new school building was officially opened by Lord Huntingfield, the Governor of Victoria, on 9 April 1937.
The town was devastated in the Black Friday bushfires in 1939.
