John Porter-Porter (3 April 1855–10 August 1939) was a unionist politician in Northern Ireland.
He was born John Porter Archdale on 3 April 1855,[1] the son of Nicholas Montgomery Archdale of Crock-na-crieve, co. Fermanagh. He studied at The King's School, Worcester[2] and Caius College, Cambridge,[3] then resided at Belle Isle in County Fermanagh. He adopted his unusual surname of Porter-Porter in 1876, replacing Archdale with Porter, in accordance with the terms of an inheritance.[4]
He served as a J.P. and Deputy Lieutenant of Co. Longford and was appointed High Sheriff of Longford for 1879 and as High Sheriff of Fermanagh for 1883.[5]
Porter-Porter was elected to the first Senate of Northern Ireland for the Ulster Unionist Party, despite his lack of political experience. He retired from the Senate in 1937,[2] and died two years later.[4] He had married Josephine, the eldest daughter of Jesse Lloyd of Co. Monaghan.[5]
