Millicent Preston-Stanley (9 September 1883 – 23 June 1955) was an Australian feminist and politician who served as the first female member of the New South Wales Legislative Assembly.

She campaigned for reductions in maternal mortality, reform in child welfare, amendments to the Health Act, and better housing.

She re-formed the Feminist Club of New South Wales and served as its president from 1920[21] to 1928 when Ada S. Holman was elected to the position.

Their purpose was primarily evangelical, and social, helping to cultivate resources and gatherings for women to attend and exchange information and skills in craftwork like sewing, knitting and so forth.
