Marvel Zombies is an upcoming American animated television miniseries created by Zeb Wells for the streaming service Disney+, based on the Marvel Comics series of the same name. It is intended to be the 16th television series in the Marvel Cinematic Universe (MCU) from Marvel Studios and is produced by Marvel Studios Animation. The series explores an alternate timeline in the multiverse introduced in the What If...? episode "What If... Zombies?!" (2021), in which a group of survivors must fight former heroes and villains who are now zombies. Wells serves as head writer and Bryan Andrews directs.

Awkwafina, David Harbour, Simu Liu, Elizabeth Olsen, Randall Park, Florence Pugh, Hailee Steinfeld, and Iman Vellani reprise their roles from prior MCU media, alongside Dominique Thorne and Todd Williams. Marvel Studios was developing several animated series in addition to What If...? by June 2021, including a spin-off series continuing the events of "What If... Zombies?!". Marvel Zombies was announced in November, along with the involvement of Wells and Andrews.

Marvel Zombies is scheduled to premiere on Disney+ on October 3, 2025, and will consist of four episodes. It will be part of Phase Six of the MCU.
