Baron Zemo (/ˈziːmoʊ/) is the name of two supervillains appearing in American comic books published by Marvel Comics. Heinrich Zemo and his son Helmut Zemo have both been depicted as a major adversary of Captain America and the Avengers, as well as the leader of the Masters of Evil, a team comprising numerous villains in the Marvel Universe.

In the 2021 radio drama podcast series Marvel's Wastelanders, two original incarnations of King Zemo (voiced by James Saito) are introduced as Helmut Zemo's successors as Dictators of the Wastelands: Herman Zemo (voiced by Ki Hong Lee) and Ash Morse (voiced by Sasha Lane).
