Demons 2 (Italian: Dèmoni 2) is a 1986 Italian horror film directed by Lamberto Bava and produced by Dario Argento. It is a sequel to Bava's 1985 film Demons and stars David Knight, Nancy Brilli, Coralina Cataldi Tassoni, as well as Argento's youngest daughter, Asia Argento, in her debut film performance at age 10. In the film, demons invade the real world through a television broadcast, turning the residents of an apartment building into bloodthirsty monsters.

Filming for Demons 2 began in May 1986, seven months after the release of the first film. Shooting took place in Hamburg, Germany, and Rome. Demons 2 was released in theatres in Italy later that year, distributed by Titanus. Following the release of Demons 2, development on a third Demons film began. The follow-up project ultimately became The Church (1989), directed by Michele Soavi, which is not narratively connected to Demons or Demons 2. But the private quarters are shown behind a wall in Demons mirroring them so the only connection is the movie house was built over the Church but it never says directly.
