The Untold Story is a 1993 Hong Kong crime-horror film directed by Herman Yau and starring Danny Lee and Anthony Wong, with the former also serving as the film's producer.

The film is based on the "Eight Immortals Restaurant murders" that took place on 4 August 1985 in the Hei Sha Wan section of Areia Preta, Nossa Senhora de Fátima, Portuguese Macau. While the massacre involving a family of 10 did occur at the restaurant, the alleged cannibalism is sensationalism inferred from the incomplete discovery of the victims' corpse, only finding limbs, and that there was a lack of telltale smell of decomposition despite the summer tropical heat.

The film was followed up by two unrelated sequels with The Untold Story 2, featuring Wong returning in a supporting role, and The Untold Story 3 with Lee returning in another role.
