how old was eddie munson when he died

Eddie Munson was approximately 20 years old when he died in Stranger Things Season 4, although there is a small in-universe continuity error that also suggests he could be 17.

Quick Scoop: Eddie Munson’s Age

• Eddie is a repeating senior at Hawkins High; dialogue indicates he should have graduated in 1984 but is still in school in 1986, which places him at about 20 years old during Season 4.

• Some fan and companion sources list his birth year as 1965, which also makes him roughly 20 in 1985–1986.

• A missing person poster shown briefly in the show lists his age as 17, which conflicts with these clues and is widely considered a production mistake or an in-universe oddity.

Why There’s Confusion

• The missing poster saying 17 has led to a lot of forum and article debate about whether he was actually a teenager or in his early twenties.

• One popular explanation is that because Eddie dies in the Upside Down—frozen in 1983—his listed age might reflect how old he would have been then, not in 1986, though this still does not cleanly match every detail.

In fandom discussions, the most accepted view is that Eddie Munson is around 20, and the “17” on the poster is either a prop error or a quirky lore point rather than his true age.
