The Last Detective is a British TV comedy drama series, broadcast on ITV between 7 February 2003 and 31 May 2007, starring Peter Davison as the title character, Detective Constable "Dangerous Davies". The series is based on the "Dangerous Davies" series of novels written by Leslie Thomas, and was filmed in the north London suburbs of Willesden, Neasden and Harlesden.

The first series aired in 2003, with three more series following it. The first, second and third series all consist of four 70-minute episodes (90-minutes with advertisements). The fourth series is slightly longer, encompassing five episodes. After a total of seventeen episodes, production company Meridian Broadcasting (later Granada Productions), who produced the programme, stated that the series had been axed due to falling viewing figures, and that the fourth series would be the last.

The Granada series was not the first time that the title character had appeared on television. He previously appeared in a TV movie, first broadcast on 4 January 1981, starring Bernard Cribbins.
