Macroom (; Irish: Maigh Chromtha) is a market town and civil parish in the barony of Muskerry West, County Cork, Ireland. It is situated in a valley of the River Sullane, about halfway between Cork city and Killarney. The name in Irish Gaelic may mean "meeting place of followers of the god Crom" or "crooked oak", the latter a reference to a large oak tree that grew in the town-square during the reign of King John. The town grew around the building of the castle by the Carew family around the same time.
