Mike Rossman (born Michael Albert DePiano on July 1, 1955) is an American former professional boxer who was the WBA light heavyweight champion of the world.

Rossman fought Víctor Galíndez for the light heavyweight championship of the world on the undercard of an Ali–Spinks rematch in September 1978.

[citation needed] In February 1979, Rossman participated in what is sometimes considered one of professional boxing's most embarrassing moments (at least in modern times).

After immediate attempts to remedy the situation failed, the fight was suspended, and rescheduled two months later in April 1979.

The pain became worse over the course of the fight, and unbearable to a point where Rossman told his father-manager after the ninth round that he could not continue.
