The Wrong Trousers is a 1993 British stop-motion animated short film co-written and directed by Nick Park, featuring his characters Wallace & Gromit, and was produced by Aardman Animations in association with Wallace and Gromit Ltd., BBC Bristol, Lionheart Television and BBC Children's International. It is the second film featuring the eccentric inventor Wallace (voiced by Peter Sallis) and his dog Gromit, following A Grand Day Out (1989). In the film, a villainous penguin, Feathers McGraw, posing as a lodger, recruits Wallace by using his techno-trousers to steal a diamond from the city museum.

The Wrong Trousers debuted in the United States on 17 December 1993, and the United Kingdom on 26 December 1993 on BBC Two. It was commercially successful, and won the Academy Award for Best Animated Short Film in 1994. It also inspired a charity fundraising day, known as "Wrong Trousers Day", one of several events.

The Wrong Trousers was followed by A Close Shave (1995), The Curse of the Were-Rabbit (2005), and A Matter of Loaf and Death (2008). Feathers McGraw returns in the 2003 video game Wallace & Gromit in Project Zoo and made a background cameo in the 2023 film Chicken Run: Dawn of the Nugget.

On 6 June 2024, it was announced a sequel to the short in the form of a feature film, Vengeance Most Fowl.
