The Jackal (Miles Warren) is a Marvel Comics Universe supervillain.

Dr. Miles Warren was once a professor of biochemistry at Empire State University. He fell in love with one of his students, Gwen Stacy. After her death, he became completely insane, developing the personality of the Jackal. He also created a clone of Gwen, and later cloned Peter Parker; this clone would take the name Ben Reilly and, years later, briefly become the Scarlet Spider, then Spider-Man. Both the Jackal and the clone of Gwen were manipulated by the Green Goblin in the Clone Saga.
