Seán South (; – 1 January 1957) was a member of an IRA military column led by Seán Garland on a raid against a Royal Ulster Constabulary barracks in Brookeborough, County Fermanagh, Northern Ireland, on New Year's Day 1957. South, along with Fergal O'Hanlon from County Monaghan, died of wounds sustained during the raid. South has subsequently been commemorated as a martyr by Republicans. Life Seán South was born in Limerick, where he was educated at Sexton Street Christian Brothers School, later working as a clerk in a local wood-importing company called McMahon's. He was a member of a number of organisations, including Clann na Poblachta (who he worked for during the 1948 election), Sinn Féin, the Gaelic League and the Legion of Mary.

He was also a member of the Knights of Columbanus. In 1949, South wrote a series of letters to his local newspaper, the Limerick Leader. These letters condemned Hollywood films for what South regarded as their immoral messages.
