Suspicion ^[1] is the title of an American television mystery drama series which aired on the NBC from 1957 through 1958. The executive producer of half of the filmed episodes (10) of Suspicion was film director Alfred Hitchcock.

The program was originally hosted by actor Dennis O'Keefe. In network repeats in 1959, Walter Abel became the host. The one-hour-long program, like others offered by Hitchcock, was designed to play on people's fears and suspicions. The first episode 'Four O'Clock', broadcast on 30 September 1957 and starring E. G. Marshall, was directed by Hitchcock himself.

Actors who appeared in this series include Claudette Colbert, Bette Davis, Eli Wallach, Roddy McDowall, Cathleen Nesbitt, James Daly, E. G. Marshall, William Shatner, Jack Klugman, Agnes Moorehead, Ross Martin, Margaret O'Brien, Rod Taylor, Audie Murphy, Harry Dean Stanton, Edmond O'Brien and Joanne Linville.
