Lillian Margaret Metge (née Grubb; 22 June 1871 – 10 May 1954) was an Anglo-Irish suffragette and women's rights campaigner. She founded the Lisburn Suffrage Society, which she left to become a militant activist, leading on an explosion at the Anglican Lisburn Cathedral in Ireland. She was imprisoned briefly, and awarded a Women's Social and Political Union Hunger Strike medal. She continued her campaign, albeit peacefully, during and after World War I.
