Balwyn North, also known as North Balwyn, is a suburb of Melbourne, Victoria, Australia, 10 km east of Melbourne's Central Business District, located within the Cities of Boroondara and Whitehorse local government areas. Balwyn North recorded a population of 21,302 at the 2021 census. It contains the localities of Greythorn and Bellevue.

Following European settlement of Melbourne, development in Balwyn North was slow and largely as agricultural land. The suburban expansion after the Second World War reached the area in the 1940s and 1950s and thousands of single dwelling houses were built across the area. Today it retains its largely residential character with small areas of retail and parkland.

The suburb shares its name with Balwyn to the south. It is named for the estate of Andrew Murray from the Gaelic bal and the Saxon wyn, meaning 'the home of the vine'. Balwyn Road and the district were named after it.

The formally recognised traditional owners for the area in which Balwyn North is located are the Wurundjeri people. The Wurundjeri people are represented by the Wurundjeri Woi Wurrung Cultural Heritage Aboriginal Corporation.

Balwyn North was one of the first Melbourne suburbs to be developed according to the pattern of postwar suburbia, with expansive, quiet residential areas designed as family homes and relatively few business districts, notably including the Riverside Estate. The original route of Bulleen Road began at the present-day corner of Kilby Road and Burke Road, but by the 1900s, its route had changed to its present-day alignment. This was a result of Elgar's Special Survey, which dragged the alignment of Burke Road further west, resulting in the surrounding road network being forced to adjust.

A Balwyn North Post Office opened on 1 April 1937. This was renamed Burke Road in 1941, when a new Balwyn North office opened at its current location. The Greythorn Post Office opened in 1951. The suburb was lampooned in the 1974 song by Australian band Skyhooks, Balwyn Calling.

Consistently among Melbourne's top 20 most exclusive postcodes, Balwyn North's status as an affluent suburb has seen middle to upper-middle-class families from surrounding localities transfer to the area to take advantage of the suburb's relatively large block sizes and proximity to some of Victoria's best private schools including those in the neighbouring suburbs.

In the 12-month period to January 2020 Balwyn North reported a median house price of A$1.46 million for a three bedroom house.
