Agatha Christie's Poirot, or simply Poirot (UK: ), is a British mystery drama television programme that aired on ITV from 8 January 1989 to 13 November 2013. The ITV show is based on many of Agatha Christie's famous crime fiction series, which revolves around the fictional private investigator Hercule Poirot. David Suchet stars as the title character. Initially produced by LWT, the series was later produced by ITV Studios. The series also aired on VisionTV in Canada, and on PBS and A&E in the US.

The programme ran for 13 series and 70 episodes in total. Each episode was adapted from a novel or short story by Christie that featured Poirot. In each episode Poirot is both the main detective in charge of the investigation of a crime (usually murder) and the protagonist at the centre of most of the episode's action. At the programme's conclusion, which finished with "Curtain: Poirot's Last Case", based on the 1975 novel of the same name, every major literary work by Christie that featured the title character had been adapted.
