Armando Bó (3 May 1914 – 8 October 1981) was an Argentine film actor, director, producer, screenwriter and score composer.

In 1956, Bó met Isabel Sarli and cast her as the lead actress in his film Thunder Among the Leaves (1957), in which she made the first full frontal nude in the history of Argentine cinema.

He later offered her the opportunity to star in El trueno entre las hojas (Thunder in the Leaves).

Bo tricked Sarli to appear naked in a scene in which she bathed in a lake, though she had previously been told she would wear a flesh-colored body stocking.

Renowned filmmaker John Waters has claimed to be a big fan of Bó's filmography, and to have been influenced by it as well.
