Macroom (; ) is a market town in County Cork, Ireland which formed in the valley of the River Sullane, about halfway between Cork city and Killarney. Its Irish Gaelic may translate as "meeting place of followers of the god Crom" or "crooked oak", the latter a reference to a large oak tree that apparently grew in the town-square during the reign of King John. Its population has grown and receded over the centuries as it went through periods of war, famine and workhouses, forced emigration and intermittent prosperity. The 2016 census recorded an urban population of 3,765 people.
