Jennifer Jane Parker is Marty McFly's girlfriend, portrayed by Claudia Wells in the first film and by Elisabeth Shue in the second and third films.

Lore & Background

In Back to the Future Part II, Doc Brown persuades Marty and Jennifer to travel to 2015 with him to help their future children. Once they arrive, Doc incapacitates Jennifer and leaves her asleep in an alley so that she does not learn about her own future; the police find her and take her to her 2015 home. She wakes up in her 2015 home, hides from the McFly family, and faints after encountering her future self. At the end of Part III she reunites with Marty in 1985, and the text of the fax she kept from 2015 about Marty's firing disappears.
