Chiller is a five-part British horror fantasy anthology television series, produced by Yorkshire Television, that first broadcast on ITV on 9 March 1995. Described by The Guardian as ITV's "answer to The X Files", the series was inspired by, but unconnected to, the 1991 Channel 4 thriller Gray Clay Dolls, which broadcast under the Chiller banner, the series featured writing contributions from renowned playwrights Stephen Gallagher, Glenn Chandler and Anthony Horowitz.

ITV Yorkshire, previously known as Yorkshire Television and commonly referred to as just YTV, is the British television service provided by ITV Broadcasting Limited for the Yorkshire franchise area on the ITV network. Until 1974, this was primarily the historic county of Yorkshire and parts of neighbouring counties served by the Emley Moor transmitter. Following a reorganisation in 1974 the transmission area was extended to include Lincolnshire, northwestern Norfolk and parts of Derbyshire and Nottinghamshire, served by the Belmont transmitter.
