This is a list of fictional characters from the DC Comics universe who are or have been depicted as antagonists of the Flash.

The Golden Age Flash enemies were all villains of the first Flash, Jay Garrick, later portrayed as living on Earth-Two after the introduction of the Silver Age Flash.

Rose and Thorn are the two personalities of a Golden Age character in DC Comics. Thorn (Rose Canton) is a woman with a split personality whose villainous personality has the ability to control plants. Initially, she and her hired thugs opposed The Flash. After being (apparently) cured of her Thorn persona, Rose married Alan Scott and had two children, Jennie-Lynn Hayden and Todd James Rice with him. After a resurgence of her madness, she committed suicide.

Years later, a second "Rose and Thorn" appeared, Rhosyn Forrest. (Before the Crisis on Infinite Earths, Rose Canton came from Earth-2 and Rose Forrest from Earth-1; see Multiverse (DC Comics)).

The Silver Age Flash enemies all lived on Earth-One and started out as enemies of the second Flash, Barry Allen, as well as the third Flash, Wally West, and the fourth, Bart Allen, after the death of Barry Allen. The Silver Age is when some enemies started to use the name Rogues. Originally, the Rogues were just a few of the Flash's enemies teaming together, but since then they have formed a lasting team, and usually a Rogue will not commit a crime by himself. The original eight Rogues were Captain Cold, Mirror Master, Heat Wave, Weather Wizard, the Trickster, Pied Piper, the Top, and Captain Boomerang. The current incarnation of the Rogues includes Captain Cold, Weather Wizard, Heat Wave, the second Mirror Master, and the new Trickster.
