Grace O'Malley (c. 1530 – c. 1603), also known as Gráinne O'Malley (Irish: Gráinne Ní Mháille), was the head of the Ó Máille dynasty in the west of Ireland, and the daughter of Eoghan Dubhdara Ó Máille (Owen Dubdara O'Malley). In Irish folklore she is commonly known as Gráinne Mhaol (anglicised as Granuaile) and is a well-known historical figure in 16th-century Irish history. Her name was also rendered in contemporary English documents in various ways, including Gráinne O'Maly, Graney O'Mally, Granny ni Maille, Grany O'Mally, Grayn Ny Mayle, Grane ne Male, Grainy O'Maly, and Granee O'Maillie.
