Everything We Know About Stranger Things Season 3, From the Premiere Date to the Cast

Executive producer Shawn Levy first revealed season three's episode count in an interview with Glamour, explaining that they'd already mapped out the story: "It'll be an eight- or nine-episode season. The number of episodes will be dictated by the amount of story that excites us. We now know what is going to happen in season three to every character." In February 2018, TVLine confirmed the episode count would be exactly eight, which matches the count of season one.

On Dec. 9, Netflix dropped the titles for each of the season's eight episodes, giving fans a small taste of what they can expect with ominous episode names like "The Case of the Missing Lifeguard" and "The Battle of Starcourt" — which happens to be the title for the last episode of the season.
