Naked Killer (Chinese: 赤裸羔羊) is a 1992 Hong Kong erotic thriller film written and produced by Wong Jing, and directed by Clarence Fok Yiu-leung.

Tinam is a cop who is undergoing a traumatic period: he shot his own brother by accident, and as a result now vomits every time he handles his gun.

Furiously determined to seek revenge, Kitty breaks into Bee's office and proceeds to kill him, his bodyguards and most of his staff.

This leads to a contract being placed on them and the assignment is entrusted to Princess, one of Sister Cindy's former protégés and a lesbian with an equally deadly young lover called Baby.

Sister Cindy proceeds to murder other people who could connect Kitty to Vivian Shang, including Tinam's superior and a witness to the groin-stabbing incident.

Princess subsequently falls into the same trap she set for Sister Cindy: when they kiss, Kitty passes on some poisoned lipstick of her own.

In the battle, Tinam kills Baby, and a furious Princess pursues him and Kitty back to Sister Cindy's home.

Sight & Sound stated that the film had "appalling dubbing" and a "muddled Nikita-like plot", but was "redeemed by virtuoso action sequences."
