An Old Man and His Dog (Chinese: 老人与狗; pinyin: lǎorényǔgǒu) is a 1993 Chinese drama film directed by Xie Jin which stars Xie Tian, Baocheng Gao, Jin Meng, Siqin Gaowa, and Feng Enhe. It is based on the novel of the same name by Zhang Xianliang. Set in the 1970s, the story revolves around Xing Laohan (Xie), and his relationship with a young lady (Siqin).

The film gained notoriety for featuring serial killer and dog breeder Cheng Peng in the film as a body double for Xie, along with including Cheng's dogs, which he fed his victim's remains to. The film was banned for two decades after its release upon the discovery of Cheng's crimes, although the ban was rescinded sometime in the 2010s.
