Blood of the Beasts (Le Sang des bêtes) is a 1949 short French documentary film written and directed by Georges Franju.

The film is a special feature on The Criterion Collection DVD for Franju's Eyes Without a Face (1960).

Franju states that he wasn't interested in the subject of slaughterhouses when he decided to make the film, but the location around the building was the Ourcq Canal, allowing him to make a documentary film.

Franju stated by using a documentary film format, he was able to use both locations as lyrical counterpoints and "to explain it as a realist while remaining a surrealist by displacing the object in another context.
