Westminster is a suburb approximately 12 kilometres north of Perth, Western Australia.

Westminster was formerly the southern part of Balga but was renamed in 1995 at the request of residents.

Between 1936 and 1955, a limestone road named "Westminster Boulevard" passed through the area.

Westminster is served by a small shopping centre, Stirling Central.

Regular bus services serve Westminster along Wanneroo Road and through the middle of the suburb.
