Keilor East or East Keilor is a suburb in Melbourne, Victoria, Australia, 13 km (8.1 mi) north-west of Melbourne's Central Business District, located within the Cities of Brimbank and Moonee Valley local government areas. Keilor East recorded a population of 15,073 at the 2021 census.

Keilor East is bounded in the west by the Maribyrnong River in the City of Brimbank, in the north by the Calder Freeway, in the east by Hoffmans Road, and in the south by Buckley Street, Steele Creek and Rosehill Road.

Keilor East Post Office opened on 1 July 1947. This was renamed Niddrie in 1956, and a new Keilor East office opened in November 1957. Lincolnville Post Office on McFarlane Street opened in 1964 and closed in 1988.

Keilor East was previously located in the former City of Keilor, though now sits partially in the City of Brimbank (west of the Albion-Jacana railway line) and the remainder in the City of Moonee Valley (east of the Albion-Jacana railway line).

Keilor East contains the Milleara Shopping Centre (previously named and still commonly known as Milleara Mall), on the corner of Milleara Road and Buckley Street, as well as the small Centreway Shopping Centre and Dinah Parade shopping strip.

Keilor East has a public primary school, Keilor Heights Primary School, St. Peters School, a private primary school, a campus of the public secondary school Essendon Keilor College, and the senior campus of the private Uniting Church school Penleigh and Essendon Grammar School.

Keilor East had many more schools in the 1980s and 1990s, such as Lincolnville Primary School, Keilor South Primary School and Overland Primary School. Lincolnville and Keilor South merged in 1988 to form Rosehill Park Primary School (on the former Keilor South Primary School site). At the end of 1993, Rosehill Park and Overland were forced to close down by the State Liberal Government of Jeff Kennett, with Keilor Heights absorbing most of their students.
