This is a list of Sliders characters, a science fiction television show that aired on the Fox network for three seasons and the Sci Fi Channel for two seasons. The show starred Jerry O'Connell as Quinn Mallory, a college student who builds a device that can transport himself and others to parallel worlds. Due to the nature of the show's similar (yet always slightly different) worlds conceit, several actors appear as different versions of the same character. The following is a list of actors who have appeared on Sliders.
