James "Diamond Jim" MacDonald, born on August 23, 1958, in Flint, Michigan, was a professional light heavyweight boxer known for his power and resilience in the ring. He began his professional career on July 10, 1982, with a first-round knockout victory over Bob Nicholson at the Phoenix Civic Plaza. Over an eight-year career, MacDonald compiled a record of 29 wins, 26 by knockout, and 11 losses.

MacDonald faced several world-class opponents, including two notable world title challenges. On June 6, 1985, he fought Michael Spinks for the WBC, WBA, and IBF World Light Heavyweight Titles at the Riviera Hotel & Casino in Las Vegas. Despite his determination, MacDonald was knocked down multiple times before the fight was stopped at 1:30 of the eighth round, resulting in a TKO loss. He earned another title shot on May 3, 1987, against Bobby Czyz for the IBF World Light Heavyweight Title at the Convention Center in Atlantic City. The bout ended in the sixth round with a TKO favouring Czyz.

MacDonald's final professional fight occurred on December 15, 1990, against Leeonzer Barber at the Civic Arena in Pittsburgh. The match concluded in the third round with a TKO loss for MacDonald, after which he retired from boxing.

Before his professional career, MacDonald served as a military police officer in the United States Marine Corps from 1978 to 1981. During his service, he distinguished himself in boxing, becoming the All-Marine Boxing Champion and winning the World CISM Games, which propelled him into his professional boxing journey.

After retiring from boxing, MacDonald settled in Kennesaw, Georgia. He battled advanced Parkinson's disease and dementia in his later years and passed away on August 19, 2023, just shy of his 65th birthday.

MacDonald's career was marked by his willingness to face top-tier competition and his significant punching power, earning him recognition and respect in the boxing community.
