Decapoda Shock is a 2011 Spanish short science fiction action parody film written, directed, co-produced, and with brief animated sequences by Javier Chillon.

Decapoda Shock shares a number of themes with Javier Chillon's first film, Die Schneider Krankheit: monstrous creatures resulting from "spatial" mutations or genetic manipulation, primarily derived from the science fiction B movies of the 1950s, the "atomic age".
