Cecily Maude O'Connell (30 June 1884 – 13 December 1965) was an Australian trade unionist and religious social worker.

[1][2][3][4] Despite being a supporter of the Labour Party, O'Connell argued for state aid to go to independent schools.

When she was 46 years old she founded the Company of Our Lady of the Blessed Sacrament, also known as the Grey Sisters, in Kewn Kreestha house in Daylesford, Victoria.

They provided cleaning, cooking, shopping and child care services for families with an ill mother or new baby.

Before she died the Grey Sisters had opened houses in Prahran, Surrey Hills, Canterbury and Croydon.
