Wallace & Gromit: Vengeance Most Fowl is a 2024 British animated comedy film produced by Aardman Animations and the BBC in association with Netflix. The sixth installment in the Wallace & Gromit series and the second to be feature-length following The Curse of the Were-Rabbit (2005), it was directed by Nick Park and Merlin Crossingham and written by Park and Mark Burton. It features the return of Feathers McGraw from The Wrong Trousers (1993), who is out for revenge on Wallace and Gromit and turns the former's latest invention on the duo to exact his vengeance. The voice cast is led by Ben Whitehead as Wallace, alongside Peter Kay, Lauren Patel, and Reece Shearsmith.

Due to difficulties with working with DreamWorks Animation during the production of The Curse of the Were-Rabbit, Park was hesitant on directing another feature-length Wallace & Gromit film for several years. Vengeance Most Fowl, which was announced in January 2022, with Park and Crossingham attached as directors, and Burton as screenwriter, was initially conceived as another 30-minute short, before expanding into a feature. The score was composed by Lorne Balfe and series composer Julian Nott.

Wallace & Gromit: Vengeance Most Fowl premiered at the American Film Institute on 27 October 2024. It was broadcast on BBC One and BBC iPlayer on 25 December in the UK and was released on Netflix internationally on 3 January 2025. After 28 days of catch-up viewing, it became the BBC's most watched scripted show since 2002. The film received critical acclaim, holding a 100% rating on the review aggregator website Rotten Tomatoes. It was nominated in the Animated Feature categories at the Academy Awards, Golden Globe Awards, Annie Awards and the BAFTAs, winning the latter. It also won the inaugural BAFTA Award for Best Children's & Family Film, in addition to being nominated for Outstanding British Film at the same ceremony.
