Daibyonin (大病人, Daibyōnin, literally "patient in serious condition"), also known as The Last Dance and more rarely The Seriously Ill, is a 1993 Japanese film directed by Juzo Itami about the final year of a successful film director suffering from cancer.

The film can be seen as a criticism of the traditional attitudes of Japanese doctors to their patients, especially the withholding of information from patients with terminal illnesses, which Itami saw as "a violation of human rights". It also touches on other end-of-life issues for the terminally ill, and how Japanese society deals with both life and death.

The film's cast includes Rentarō Mikuni (Buhei Mukai, the film director), Masahiko Tsugawa (Doctor Ogata) and Nobuko Miyamoto (Buhei's wife). Mikuni was nominated for Best Actor at the 1994 Japanese Academy Awards for his role in both Daibyonin and Tsuribaka nisshi 6.
