Trigger Happy TV is a hidden camera/practical joke comedy television series. The original British edition of the show, produced by Absolutely Productions, starred Dom Joly and ran for three series on the British television channel Channel 4 from 2000 to 2003. Joly made a name for himself as the sole star of the show, which he produced and directed with cameraman Sam Cadman. Trigger Happy TV and World Shut Your Mouth, his other major show, would both be categorised as deadpan or "dry humour".

A hidden camera or spy camera is a camera used to photograph or record subjects, often people, without their knowledge. The camera may be considered "hidden" because it is not visible to the subject being filmed, or is disguised as another object. Hidden cameras are often considered a surveillance tool.
