Werewolf by Night is an American television special directed by Michael Giacchino and written by Heather Quinn and Peter Cameron for the streaming service Disney+, based on the Marvel Comics featuring the character of the same name. It is the first Marvel Studios Special Presentation in the Marvel Cinematic Universe (MCU), sharing continuity with the films and television series of the franchise. The special was produced by Marvel Studios and follows a secret group of monster hunters as they compete for a powerful relic while going up against a dangerous monster.

Gael García Bernal stars in the special as Jack Russell / Werewolf by Night, along with Laura Donnelly and Harriet Sansom Harris. Development of the special had begun by August 2021, with Bernal cast that November. Giacchino was revealed to be directing in March 2022, ahead of the start of filming later that month at Trilith Studios in Atlanta, Georgia, concluding in late April. The special was formally announced in September, when Giacchino revealed he was also composing.

Werewolf by Night was released on October 7, 2022, as part of Phase Four of the MCU. The special received positive reviews from critics, with praise for its use of practical effects, the black-and-white cinematography, performances (particularly Bernal and Donnelly), Giacchino's direction and score, and its story, with many noting its departure from previous MCU media. A fully colored version of the special, known as Werewolf by Night in Color, was released on October 20, 2023.
