Trentham is a small town in the Hepburn Shire Local government area, Victoria, Australia. At the 2001 census, Trentham had a population of 700.
Located at an altitude of 700 metres in ancient volcanic highlands 97 kilometres northwest of Melbourne, Trentham is surrounded by the dense eucalypts of Wombat State Forest on three sides, whilst to the north the highlands fall away to the vast plains of inland Victoria down the Campaspe River.
Although pastoral runs were taken up in the area as early as 1838, Trentham was first settled by gold prospectors in the 1850s, and developed as the trees of Wombat Forest became a valuable resource for timber, which built up the town. A railway line arrived in 1890 and at its peak carried up to 21,000 tonnes of freight (mostly timber) annually. However, in the 1950s the railway declined as better roads were built to connect the town with the major settlements of Victoria, and it was closed during the 1970s.
Potato growing and grazing became the mainstays of the town’s economy until tourism developed in the 1970s.
