Michael Anthony Busch (born July 7, 1968) is an American former professional baseball player and manager.

Busch is an alumnus of Iowa State University where he played both baseball and American football.

He made his Major League Baseball debut with the Los Angeles Dodgers on August 30, 1995, becoming the first replacement player to be promoted to a regular MLB roster after the 1994 Major League Baseball strike.

Because of his status as a replacement player, Busch was never allowed membership in the MLBPA.

On December 1, 2008, the Schaumburg Flyers of the Northern League announced Mike Busch as their new manager for the 2009 season.
