Tales of Suspense is a comic book series published by Marvel Comics from 1959-1968. Although it started out as a science fiction/horror anthology, the emerging popularity of superheroes led to such characters being featured regularly, eventually pushing out the non-superhero suspense stories. Iron Man first appeared in #39, and was a regular feature until the series ended. The Watcher narrated "Tales of the Watcher" from #49-58. Captain America appeared in the Iron Man story in #58 and had his own feature from #59 until the series ended with #99, after which Tales of Suspense was retitled Captain America.

Iron Man's adventures after #99 continued in Iron Man and Sub-Mariner #1, and then in Iron Man (volume 1) #1; Captain America's adventures in Captain America #100.
