"Tom Thumb Tempest" is the 22nd episode of Stingray, a British Supermarionation television series created by Gerry and Sylvia Anderson and produced by their company AP Films (APF) for ITC Entertainment. Written by Alan Fennell and directed by Alan Pattillo, it was first broadcast on 28 February 1965 on ATV London. In "Tom Thumb Tempest", Troy has a nightmare in which Stingray and its crew are miniaturised. The use of life-sized sets to convey the shrinking of the puppet characters has attracted a mixed response from commentators.
