What is the name of the high school club led by Eddie Munson in Stranger Things?

The high school club led by Eddie Munson in Stranger Things is the Hellfire Club.

The Hellfire Club is a Dungeons & Dragons society at Hawkins High School. Eddie Munson serves as its Dungeon Master and leader, guiding campaigns for students who gather to play the tabletop role-playing game. Mike Wheeler, Dustin Henderson, and Lucas Sinclair are among its members in season 4, with Lucas struggling to balance the club against his basketball commitments.

The club’s name and theatrical presentation make it look sinister to outsiders, especially after Chrissy Cunningham is murdered in Eddie’s trailer. Hawkins residents incorrectly connect the group’s Dungeons & Dragons imagery to Satanism, reflecting the real-world “Satanic panic” surrounding the game in the 1980s.

The club is introduced prominently in “Chapter One: The Hellfire Club,” the opening episode of season 4. Its campaign also establishes the season’s use of Vecna as a Dungeons & Dragons-inspired name for the supernatural villain, though the fictional monster and the show’s antagonist are not literally the same being.
