Auburn is an electoral district of the Legislative Assembly of the Australian state of New South Wales in Sydney's West.

On its current boundaries, Auburn includes the suburbs of Auburn, Berala, Birrong, Lidcombe, Potts Hill, Sefton, Rookwood, Wentworth Point and parts of Bankstown, Bass Hill, Chester Hill, Silverwater and Yagoona.

It is considered a part of Labor's heartland in Western Sydney.

The seat was once vacant for four months; between December, 1955 and March, 1956; as a result of the death of Edgar Dring.

A by-election was not held, given the relatively short amount of time left until the 1956 New South Wales state election.
