Bayswater is a residential and industrial suburb in Melbourne, Victoria, Australia, 27 km (17 mi) east of Melbourne's Central Business District, located within the City of Knox local government area. Bayswater recorded a population of 12,262 at the 2021 census.

The first Post Office in the area was Scoresby North, which opened on 8 May 1882 and renamed Macauley in 1884. When the railway arrived in 1889, a Bayswater office near the station replaced Macauley. In 1998 Bayswater Village (at the shopping centre of that name) office replaced Bayswater.

In the late 1940s, a number of German Templers (just released from the Tatura Internment Camp) settled in Bayswater and Boronia. Part of the Temple Society Australia, they built a Community Centre (1961) in Elizabeth Street and a Retirement Village, as well as Nursing Home Tabulam, in partnership with the Australian German Welfare Society (AGWS).

The Bayswater Wine Cellar is the oldest building in the region, erected in the mid 19th century to service loggers that travelled between the city and the Dandenongs. It was sold to a developer in late 2017.

On 17 November 1969, Bayswater Fire Brigade was registered with CFA. The Brigade became operational in January 1970 and attended its first fire call on 22 January. However, a site for the Fire Station had not yet been established so the Brigade vehicle was parked under a tarp at the rear of a service station on the corner of Mountain Highway and Highmoor Avenue, Bayswater. On Good Friday 1970 a tin shed was erected to house the Brigade vehicle and other operational equipment.

In 1973, the tin shed was relocated to a site adjacent to the Scoresby Road railway crossing until the present Fire Station was built in 1976. In 2008, the Brigade leased an additional building on the same site to be used for administration, meetings and indoor training.

Schools currently in Bayswater include Our Lady of Lourdes Primary School, Bayswater Primary School, Bayswater South Primary School, Bayswater West Primary School and Bayswater Secondary College (formerly Bayswater High School).

The Bayswater library is located inside the Mountain High Shopping Centre.

Bayswater Station is located near the Mountain Highway, and is on the Belgrave line.
