Mackies was a textile machinery engineering plant and foundry in Northern Ireland until 1999. At its height, James Mackie & Sons was one of the largest employers in Belfast and a major supplier of munitions during World War II. In 1955 the company built a factory in India for the manufacture of machinery for jute mills. This was taken over by the Government of India in 1978. Through various changes it still exists as Lagan Engineering Company Ltd, a joint venture with the Government of India.
