Dr. Lamb (羔羊醫生) is a 1992 Hong Kong crime film directed by Danny Lee and Billy Tang.

The film stars Lee, Simon Yam and Kent Cheng.

The film is allegedly based on crimes actually committed in 1982 by Hong Kong serial killer Lam Kor-wan.

HorrorNews.net gave the film a mixed review, writing, "Dr. Lamb skips back and forth between brutal violence that is seriously treated, and ridiculously over-the-top, even slapsticky sequences that seem out-of-place in what is meant to be a crime film based on a true story.

"[2] Joey O'Bryan of The Austin Chronicle awarded the film three out of five stars, stating, "A film that pushes the limits of bad taste in several key scenes, Dr. Lamb is a slick, and sick, exploitation item that both repels the viewer with its images of disturbing, misogynistic violence, in addition to tickling them with repulsive black humor à la early John Waters.
