WandaVision is an American television miniseries created by Jac Schaeffer for the streaming service Disney+, based on the Marvel Comics characters Wanda Maximoff / Scarlet Witch and Vision. Set in the Marvel Cinematic Universe (MCU), it shares continuity with the films of the franchise, and takes place after the events of the film Avengers: Endgame (2019). WandaVision is produced by Marvel Studios, with Schaeffer serving as head writer and Matt Shakman directing.

Elizabeth Olsen and Paul Bettany reprise their respective roles as Wanda Maximoff and Vision from the film series, while Debra Jo Rupp, Fred Melamed, Kathryn Hahn, Teyonah Parris, Randall Park, Kat Dennings, and Evan Peters also star. By September 2018, Marvel Studios was developing a number of limited series for Disney+, centered on supporting characters from the MCU films such as Wanda and Vision, with Olsen and Bettany returning. Schaeffer was hired in January 2019, the series was officially announced that April, and Shakman joined in August. The series homages past sitcoms, with Wanda and Vision living in a reality that takes them through different decades of television tropes. Filming began in Atlanta, Georgia in November 2019, before production halted in March 2020 due to the COVID-19 pandemic. Production resumed in Los Angeles in September 2020 and completed that November.  

WandaVision premiered with its first two episodes on January 15, 2021, and will run for nine episodes until March 5. It is the first series in Phase Four of the MCU. The series was praised by critics for its homages to past sitcoms, dark tonal shifts, and Olsen and Bettany's performances.
