A Touch of Frost is a British television detective mystery drama series starring David Jason produced by Yorkshire Television (later ITV Studios) for ITV from 6 December 1992 until 5 April 2010, initially based on the Frost novels by R. D. Wingfield.

Comic relief is provided by Frost's interactions with the bureaucratically-minded Superintendent Norman "Horn-rimmed Harry" Mullett, played by Bruce Alexander.

A number of young actors had their major debut as supporting cast in the show, including: Matt Bardock, Ben Daniels, Neil Stuke, Mark Letheren, Colin Buchanan, Jason Maza, Jim Sturgess, Damian Lewis and Marc Warren.

In SE1E1 a character mentions going to Bishop's Stortford, implying it is a short journey away and thus in the Hertfordshire or Essex area.

In SE2E3 a suspect talks about "Driving over to Chelmsford", implying reasonable proximity to Denton, again placing the action in the Herts/Essex area.

Paperwork given to Frost and other characters refers to Denton station as being part of the Thames Valley Police.

In SE4E1 Frost and Toolan observe a train passing, consisting of a British Rail Class 141 Pacer in West Yorkshire Metro red and cream livery coupled with a British Rail Class 142 Pacer in BR Provincial Sector blue livery.

At a press conference in London on 15 September 2008, David Jason announced that he would be quitting the role of DI Jack Frost.

The series is based on the novels of R. D. Wingfield: By discarding several minor sub-plots in "Frost at Christmas", the two major cases were able to be investigated in the one episode, being the pilot "Care and Protection".

Despite the show still being produced when the last two novels were written, they were never used as source material for episodes, possibly due to their more graphic subject matter.

The iconic saxophone solo heard during the show's theme music was performed by Barbara Thompson.

However, from 2012, ITV3 HD have been broadcasting a growing number of episodes of the series in high definition, remastered from the original 16mm source.

Other countries that have aired the series include Belgium, Croatia, Denmark, Finland, France, Japan, Norway and Sweden.
