Turn-On is an American surreal sketch comedy series created by Digby Wolfe and George Schlatter that aired once on ABC on Wednesday, February 5, 1969. Only one episode was shown partially before being pulled from ABC's airing schedule, leaving another episode unaired. The show has since been considered one of the most infamous flops in TV history, with significantly low initial ratings and negative critical reception.

Turn-On's sole broadcast episode replaced the Wednesday episode of Peyton Place - in fact, it was even referenced on the show itself, where, in the opening, Tim Conway refers to the show as "Peyton Re-Place". Among the cast were Teresa Graves (who would join the Laugh-In cast that fall), Hamilton Camp, and Chuck McCann. The writing staff included Albert Brooks. The guest host for the first episode was Tim Conway, who also participated in certain sketches. Schlatter and Ed Friendly, who had previously been the producers of Rowan & Martin's Laugh-In, were contracted by Bristol-Myers to develop the show, and provided it to ABC for a projected 13-week run after NBC and CBS rejected it.
