Everything about the cast of Stranger Things, the Duffer Brothers' Netflix series that ran from 2016 to 2025. The set covers the main cast only: the performers billed in the opening credits at any point across the show's run, not the deep bench of recurring townspeople, lab staff, and one-season guests. Name the actors who played each role, match each headshot to a name, snap each character to the performer behind them, pick the real regulars out of a grid of same-era decoys, complete the show's most quoted lines, and answer real trivia about how the series was made. The answer is always the actor, never the character. Cast sourced from billing order and corroborated against Wikidata.
