Micky Ward (born October 4, 1965), nicknamed Irish, is a retired American junior welterweight professional boxer and a former WBU champion from Lowell, Massachusetts. He is widely known as the protagonist in the 2010 feature film based on his career titled The Fighter, in which he is portrayed by Mark Wahlberg, and culminating with his title bout against Shea Neary.

Ward was a three-time New England Golden Gloves champion boxer who turned pro in 1985, winning his first fourteen fights. However, his career leveled off, and after losing four consecutive fights in 1990/91, Ward took a hiatus from boxing.

During Ward's time away from the sport, he used some of the funds from his day job on a road-paving crew to have surgery on his right hand, with which he had problems during several bouts. The surgery used some of the bone from Ward's pelvis to strengthen and fuse the bones in his hand. His half-brother, former boxer Dicky Eklund, who was struggling with drug addiction and had just been released from jail on charges including drug possession, convinced Ward to take up the sport again.
