Conor Clune (Irish name Conchobhair Mac Clúin; 1893 – 21 November 1920) was one of three men along with Dick McKee and Peadar Clancy killed in controversial circumstances in Dublin Castle on Bloody Sunday, 1920, a day that also saw the killing of a network of British spies by the "Squad" unit of the Irish Republican Army and the killing of 14 people in Croke Park by British forces. Clune was 27 years old.
Clune was born in the village of Quin, County Clare, the son of John and Bridget Clune (née Walsh) of Kilkishen. Clune was one of a family of seven boys and three girls. His uncle was Patrick Clune, Bishop of Perth, Western Australia, who became the first Archbishop of Perth in 1913. He was educated at the local National School and St. Flannan's College, Ennis. A Gaelic League enthusiast, he also spent some time at Ring Irish College, Colaiste na Rinne, County Waterford. From a young age he was active in Gaelic League circles, and spoke Irish on every occasion possible.
Clune was at one time a member of the National Volunteers, the military organisation led by John Redmond that resulted from the 1914 split in the Irish Volunteers. He does not appear to have been a member of the Irish Volunteers, although the commemorative plaque in Dublin Castle refers to him as "Volunteer Conor Clune" (see picture). However, he was devoted to the Irish language and was involved with the Gaelic League.
