'''''Agatha Christie's Great Detectives Poirot and Marple''''' (アガサクリスティーの名探偵ポワロとマープル '''''Agasa Kurisutī no Meitantei Powaro to Māpuru?''''') is an anime television series that adapted several Creator/AgathaChristie stories about Literature/HerculePoirot and Literature/MissMarple. Run from 2004 to 2005, a total of 39 episodes.

A new character named Mabel West, Miss Marple's great-niece, who becomes Poirot's junior assistant, is used to connect the two detectives. The series is a generally faithful adaptation of the original stories given the time constraints (typically one 25 minute episode for a short story, four episodes for a novel). Despite being a modern Japanese adaptation, the original (mainly English) locations and time period are retained. The most obvious story change is the addition of Mabel West and her pet duck, Oliver. However apart from her soliloquies, most of her lines are taken from the incidental dialogue of other characters in the original stories, so her presence does not materially alter the plot development.
