Baby Blood (titled The Evil Within in the United States) is a French horror film directed and co-written by Alain Robak, and starring Emmanuelle Escourrou and Jean-François Galotte. The film is about a woman named Yanka whose womb is invaded by a parasite that desires human blood. Yanka heeds the demand of blood for the creature until it requests to be carried to the sea where it was originally spawned.

The film was shown at the Avoriaz Fantasy Film Festival and the Sarasota French Film Festival in 1990. At Avoriaz, it became the first film to win a Jury Award despite not being in competition. In 2008, a sequel to the film was released titled Lady Blood.
