Stranger Things debuted on Netflix in 2016 and was quickly renewed for a second season, premiering in 2017.
Stranger Things season 3 premieres on Netflix sometime in 2019.
The Duffer brothers and company are going back to the Upside Down (and Hawkins) sooner than we thought, as production of season 3 of Stranger Things will begin on Monday, April 23.
Fans have been eagerly waiting for details on season 3, and while there are no plot details yet, a filming date has now been revealed.
