The works of Robert E. Howard have been adapted into multiple media, such as the two Conan films released in the 1980s starring Arnold Schwarzenegger. In addition to the Conan films, other adaptations have included Kull the Conqueror (1997) and Solomon Kane (2009). In television, the anthology series Thriller (1961) led the adaptations with an episode based on the short story "Pigeons from Hell". The bulk of the adaptations have, however, been based on Conan with two animated and one live action series. Multiple audio dramas have been adapted, from professional audio books and plays to LibriVox recordings of works in the public domain. Computer games have focussed on Conan, beginning with Conan: Hall of Volta (1984) and continuing on to the MMO Age of Conan: Hyborian Adventures (2008). The first table-top roleplaying game based on Howard's works was TSR's "Conan Unchained!" (1984) for their game Advanced Dungeons & Dragons. The first comic book adaptation was in the Mexican Cuentos de Abuelito – La Reina de la Costa Negra No. 17 (1952). Howard-related comic books continued to be published to the present day.
Howard is an ongoing inspiration for and influence on heavy metal music. Several bands have adapted Howard's works to tracks or entire albums. The British metal band Bal-Sagoth is named after Howard's story "The Gods of Bal-Sagoth".
