Quambatook is a town in northern Victoria, Australia. The town is located on the Avoca River in the Shire of Gannawarra local government area, 302 kilometres (188 mi) from the state capital, Melbourne. At the 2011 census, Quambatook had a population of 361.
Quambatook was settled following the end of the Victorian gold rush of the 1850s. Resumption of large squatter's land holdings for closer settlement in the 1870s lead to Quambatook becoming one of Victoria's leading wheat and sheep producing areas. Quambatook Post Office opened on 1 September 1879.
Quambatook has been recognised as the tractor pulling capital of Australia with an annual competition, the Australian Tractor Pulling Championships, held at Easter since 1976. In fact, the town's motto is 'Land of wheat and wool, home of the tractor pull'. The town is the birthplace of country music performer John Williamson, who has written a musical named for the town.
Golfers play at the course of the Quambatook Golf Club on Boort Road.
