Segundo Víctor Aurelio Chomón y Ruiz (also Chomont or Chaumont French: [ʃomɔ̃]; 17 October 1871 – 2 May 1929) was a pioneering Spanish film director, cinematographer and screenwriter.

He produced many short films in France while working for Pathé Frères and has been compared to Georges Méliès, due to his frequent camera tricks and optical illusions.

Born in Aragon (Spain), Segundo de Chomón reportedly got into film through the efforts of his French actress wife, Julienne Mathieu, who appeared in early Pathé Frères productions and worked in some special effects Parisian workshops like Thuillier's studio.

After 1917, Chomón principally worked on creating visual effects for the films of others, including Guido Brignone's Maciste in Hell (1925) and Abel Gance's Napoléon (1927).

The very year that Chomón died, the Surrealists organized a soirée that would rehabilitate the artistic reputation of Georges Méliès and to begin the long process of recovering his films.

Chomón was effectively forgotten in the wake of his death, though over time silent film collectors began to recognize some of his shorts and he was dubbed "The Spanish Méliès" in English-speaking lands.

The Italian film Cabiria (where he was director of photography & special FX) featured what may have been the first "dolly shot" in the movies, utilizing a device built by Chomón.
