Deep Blood, also known as Sharks and Sangue negli abissi (literally: "Blood in the Abyss"), is a 1989 Italian sharksploitation drama.

The credited director Raffaele Donato (as Raf Donato) only directed the first scene in which the boys gather to seal their blood pact, while the remainder of the film was directed and photographed by Joe D'Amato, who also co-produced the film through his company Filmirage in conjunction with Variety Film.
