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 is set in the alternate timeline introduced in the "What If... Zombies?!" episode of the animated series What If...? (2021). Continuing from that episode, Marvel Zombies follows a group of survivors who fight against former heroes and villains that have been turned into zombies. Bryan Andrews served as showrunner and director, with Wells as head writer.

The series features an ensemble cast including Awkwafina, David Harbour, Simu Liu, Elizabeth Olsen, Randall Park, Florence Pugh, Hailee Steinfeld, Dominique Thorne, and Iman Vellani, reprising their roles from previous MCU media, alongside Todd Williams. Marvel Studios was developing several animated series in addition to What If...? by June 2021, including a spin-off based on "What If... Zombies?!" which was announced in November. Wells and Andrews were both involved by then. The series features the same animation style as What If...?, with Stellar Creative Lab returning from that series to provide the animation. It will be Marvel Studios Animation's first series to be rated TV-MA.

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.
