What is the original language of Stranger Things?

The original language of Stranger Things is English.

Stranger Things is an American television series created by Matt and Ross Duffer for Netflix, and its original dialogue is in English. The story is set primarily in the fictional Indiana town of Hawkins, where the characters investigate disappearances, secret experiments, and supernatural forces during the 1980s.

The series includes characters from different countries and settings, especially in later seasons. Russian dialogue appears in the Kamchatka storyline, and characters sometimes speak other languages in international scenes, but those moments do not change the show’s original language.

German, French, and Spanish are available as dubbed or subtitled options on many Netflix services, depending on region. They are translations or alternate audio tracks, not the language in which the series was originally produced and performed.
