​MIDLETON, or Middleton, a market town of Co. Cork, Ireland, on the river Owenacurra, 13 m. E. of Cork by the Youghal branch of the Great Southern & Western railway. Pop. (1901), 3361. The river here enters a branch of Cork harbour. The surrounding hilly country is pleasant and fertile, and furnishes the town with a good agricultural trade. There are also whisky-distilleries. Ballinacurra, 1½ m. south on the estuary, serves as a small port. The grammar school was founded in 1696, and here among its students were John Philpot Curran and Isaac Butt. Midleton is governed by an urban district council.
