Michael William Donald (born July 11, 1955) is an American professional golfer.

He won 1974 National Junior College Athletic Association (NJCAA) title while playing at Broward Community College and also attended Georgia Southern University.

Donald's sole win on the PGA Tour was the 1989 Anheuser-Busch Golf Classic.

Donald missed a 15-foot par putt on the 18th hole of the Monday playoff which would have given him victory.

In the 1990 Masters Tournament Donald tied the record for the lowest opening round score in the history of the tournament, shooting an 8-under-par 64 to equal the lowest first round at Augusta by Lloyd Mangrum in 1940.
