Santiago Segura Silva (born July 17, 1965) is a Spanish film actor, scriptwriter, producer and director.

Santiago was born in the Carabanchel neighbourhood in Madrid. After studying Arts at the Complutense University of Madrid, he decided to pursue a career as a film-maker and in 1989 he directed the short Relatos de medianoche with a budget of 7000 pesetas (around US$50). In 1992 he went on to direct his first professional short "Evilio", followed with "Perturbado" in 1993.

In 1993 he had a small role in Alex de la Iglesia's film Acción mutante. Two years later he starred in El día de la Bestia, from the same director and that role made him famous in Spain. In 1998 he directed the film that brought him to stardom, Torrente: El brazo tonto de la ley (1998), in which he also acted as the lead character José Luis Torrente. Its popularity led to a sequel (Torrente 2: Misión en Marbella) and a computer game (Torrente: El juego).

Torrente 2: Misión en Marbella made €22,838,500 at the Spanish box office, becoming the highest grossing Spanish film of all time. Torrente 3: El Protector, the third film in the series, was released in September 2005. Its advertising campaign parodied Batman Begins, using the phrase "Torrente Acabado" ("Torrente Finished"). Although he declared Torrente 3: El Protector would be the last of the Torrente series, he is currently casting people for Torrente 4.

He has since made his way into American culture by making appearances in movies such as Hellboy, Perdita Durango, Agent Cody Banks 2: Destination London and Blade 2.

Because of his success, Santiago Segura has become a producer. He owns Amiguetes Entertainment company and has produced Promedio Rojo (featuring Nicolás López).
