Harry Simms Hersh (December 25, 1911 – February 11, 1932) was an American labor leader from Springfield, Massachusetts.

On February 10, 1932, Simms was shot near Brush Creek in Knox County, Kentucky by a sheriff's deputy who also worked as a mine guard for the local coal company.

Simms died of his wound at Barbourville Hospital the next day.

He was memorialized in a ballad, "The Death of Harry Simms" by Aunt Molly Jackson and Jim Garland,[1] and his funeral service at the Bronx Coliseum attracted a crowd of some 20,000 people.

Tao Rodriguez Seeger has performed a cover version of the song with the Allegro Youth Orchestra.
