Timboon /tɪmˈbuːn, ˈtɪmbən/ is a town in the Western District of Victoria, Australia. The town is in the Shire of Corangamite local government area, located approximately 213 kilometres (132 mi) south-west of the state capital, Melbourne. In the 2021 census, Timboon had a population of 830 people.

The main industries within the region are dairying, forestry, and lemon and lime farming.

Prior to the arrival of Europeans, the area was inhabited by people from the Girawurung Aboriginal language group. It is believed that the Timboon's name comes from the local Aboriginal word 'timboun' which was a word used to describe pieces of rock used to open mussels.

The first white man in the area was Daniel Curdie. In 1845 he followed the river that bears his name to its mouth at Peterborough. The river flowed through thick forest at the time. The first settlers to move into the area were the Callaways. They were English immigrants who selected land in the Heytesbury Forest in 1875. They had to clear the forest to the west and north of the present township. A small settlement on the banks of the Curdies River that never developed called Curdies River was the original destination for a proposed railway.

A more suitable site was chosen in 1877 on the banks of Powers Creek was known as “New Timboon”. "Old Timboon" was the site of the original Camperdown township. The town began to grow as new settlers were attracted to the area. The first school opened in 1883. By 1889 the township of “New Timboon” offered land for sale confident of the coming of the railway to the area. The town had a general store, butcher and blacksmiths by 1891. In 1892 the railway arrived, the Timboon branch line that construction had started in 1889 at Camperdown.

The first major produce of the area was timber, the train would carry the timber out and return with all the provision a township would require. As the country opened up dairy farming became popular, the production of milk, cheese and butter are still central to the local economy. There is still substantial lemon and lime farming.

The Timboon railway line that opened in 1892 was closed in 1986. The railway line featured several trestle bridges including the now restored Timboon Trestle bridge. The Timboon to Camperdown rail trail now follows the old route taken by the railway. The local railway station that closed along with the railway and the building is now home to a distillery. The Post Office in the township opened on 7 March 1887. Two earlier offices named Timboon were opened near Camperdown, the first one operated from 1849 to 1852, the second after the town relocated, opening in 1853, was renamed Camperdown in 1854.

The Heytesbury Forest east of Timboon underwent clearing for additional dairy farms during 1928-33, and later from 1956 to 1975 the Heytesbury Settlement Scheme released 43,000 ha on which 378 farms were established. The Cobden butter and cheese factory opened a branch at Timboon in 1950. A hospital was opened in 1955, and a high school in 1960.
