The Blood of Fu Manchu (German: Der Todeskuss des Dr. Fu Man Chu, lit. 'The Death-Kiss of Dr. Fu Manchu', Spanish: Fu-Manchú y el beso de la muerte), also known as Kiss of Death, Kiss and Kill (U.S. title) and Against All Odds (original U.S. video title), is a 1968 British adventure crime film directed by Jesús Franco, based on the fictional Asian villain Dr. Fu Manchu created by Sax Rohmer. It was the fourth film in a series, and was preceded by The Vengeance of Fu Manchu. The Castle of Fu Manchu followed in 1969.

It was produced by Harry Alan Towers for Udastex Films. It starred Christopher Lee as Dr. Fu Manchu, Richard Greene as Scotland Yard detective Nayland Smith, and Howard Marion-Crawford as Dr. Petrie. The film was filmed in Spain and Brazil. Shirley Eaton appears in a scene that she claimed she was never paid for; apparently, the director Jesús Franco had inserted some stock footage of her from one of her films (The Girl from Rio (1968)) into the film without telling her. She only found out years later that she had been in a Fu Manchu film.
