Yarra Junction is a town in Victoria, Australia, 55 km (34 mi) east from Melbourne's central business district. It sits at the junction of the Yarra and Little Yarra Rivers. Its local government area is the Shire of Yarra Ranges. At the 2011 census, Yarra Junction had a population of 2,297.
The Post Office opened on 20 November 1901, a week after the railway arrived.
Yarra Junction was the junction station for the Powelltown Tramway, a three-foot gauge line, between 1913 and 1945.
It has five schools, Upper Yarra Secondary College, Yarra Junction Primary School, St Joseph's Primary School and the Little Yarra Steiner School. It is also home to the Cire Community School (previously called Yarra Valley Community School), an independent school for students for whom mainstream schooling has not been successful.
In addition to these schools, there is also a rural country campus for Caulfield Grammar School. The Yarra Junction Campus was established in 1949 and it was the first of its kind in Australia.
The town has an Australian Rules football team competing in the Yarra Valley Mountain District Football League. Its most famous product was former Richmond premiership ruckman Jack Dyer, also known as Captain Blood, who grew up in the town before moving to Melbourne in his late teens for school.
