Margaret Anna Cusack (in religion Mary Francis Clare Cusack; 6 May 1829 – 5 June 1899), also known as Mother Margaret and the Nun of Kenmare, was a former Irish Catholic nun who founded the Sisters of St. Joseph of Peace before returning to Anglicanism (the faith of her youth). She lived in Ireland, England, and the United States.

By 1870 more than 200,000 copies of her works which ranged from biographies of saints to pamphlets on social issues had circulated throughout the world, the proceeds from which went towards victims of the Famine of 1879 and helping to feed the poor. An independent and controversial figure, Cusack was a passionate Irish nationalist, often at odds with the ecclesiastical hierarchy.
