Joyce Byers (portrayed by Winona Ryder ) is the mother of Will and Jonathan Byers and is divorced from Lonnie Byers, the father of her two children. Joyce is a very caring and strong-willed woman who works as a retail clerk at Melvald's General Store in downtown Hawkins. She was born and raised in Hawkins and she attended Hawkins High School with the future chief of police, Jim Hopper, and her Season Two love interest, Bob Newby (who is later unfortunately killed by a demogorgon). In Season Three, she is planning to sell her house and move out of Hawkins, much to the dismay of Hopper who tries to convince her to go on a date with him. Even though she does have feelings for him, Joyce tries to avoid getting in another relationship. She is mainly more interested in figuring out why the magnets in her house keep falling off her fridge (to the extent that she does not show up to the date that they had planned together) and while investigating the reason behind this, she and Hopper uncover a Russian conspiracy. After infiltrating a Russian lab beneath the new Starcourt Mall, where the Russians have opened another portal into the Upside Down, Joyce is forced to close the portal by turning off the Russian machine used to open it with Hopper in the room, and Hopper ends up being “killed”. Joyce becomes a mother figure to Eleven after taking her in when Hopper supposedly died. The Byers Family and Eleven move out of Hawkins three months after Hopper's death.
