"Black Tom" Cassidy (Thomas Samuel Eamon Cassidy) is a fictional supervillain appearing in American comic books published by Marvel Comics. The character is usually depicted as an enemy of the X-Men, and archenemy of Banshee. In addition to fighting the X-Men, he has clashed with Deadpool a number of times.

Black Tom is a mutant who can manipulate, bond with, and project energy through plant life. He was the black sheep of a prominent Irish family. X-Men member Banshee is his cousin. Tom secretly raised Banshee’s daughter Siryn, of whose existence Banshee was unaware, and conscripted her into his criminal gang. Black Tom was also a longtime criminal partner of the super-strong villain Juggernaut, until Juggernaut's reformation.

Created by writer Chris Claremont and artist Dave Cockrum, Black Tom Cassidy first fully appeared in Uncanny X-Men #101 (October 1976).

Black Tom was born in Dublin. He is the cousin of Sean Cassidy, the Banshee, a member of the X-Men. He was also once the only friend of the Juggernaut.

His original principal power was that he could generate blasts of heat through a wooden medium, such as the shillelagh that he often carries. He has a rivalry with Sean, mainly because Sean won both Cassidy Keep, their estate, and the family fortune from Tom in a game of dice. They were also rivals for a woman named Maeve Rourke, whom Sean married.
