Nancy Wheeler, the character in Stranger Things, is written to be about 16 years old in Season 1 and around 18–20 years old by Seasons 4–5, since she is a high school junior/senior and then post–time jump.

Nancy’s age in the show

• Nancy’s in-universe birth year is given as 1967, which makes her about 16 in Season 1 (set in 1983).

• By later seasons, especially the upcoming or current Season 5 set a few years later, she is listed as about 19–20 years old, depending on the source.

Actress’s real age

• Nancy is played by Natalia Dyer, who was born on January 13, 1995.

• As of 2025, this makes Natalia Dyer 30 years old, so she is roughly a decade older than Nancy in the later seasons.
