Máire Drumm was the vice-president of Sinn Féin and a commander in Cumann na mBan. She was killed by Ulster loyalists while recovering from an eye operation in Belfast's Mater Hospital.

Cumann na mBan, abbreviated C na mB, is an Irish republican women's paramilitary organisation formed in Dublin on 2 April 1914, merging with and dissolving Inghinidhe na hÉireann, and in 1916, it became an auxiliary of the Irish Volunteers. Although it was otherwise an independent organisation, its executive was subordinate to that of the Irish Volunteers, and later, the Irish Republican Army.
