Michael John Mackey (12 July 1912 – 13 September 1982) was an Irish hurler who played as a centre-forward at senior level for the Limerick county team. Born in Castleconnell, County Limerick, Mackey first arrived on the inter-county scene at the age of seventeen when he first linked up with the Limerick minor team, before later lining out with the junior side. He made his senior debut in the 1930–31 National League. Mackey went on to play a key part for Limerick during a golden age for the team, and won three All-Ireland medals, five Munster medals and five National Hurling League medals. An All-Ireland runner-up on two occasions, Mackey also captained the team to two All-Ireland victories.
