The Wrong Tros is a 1993 British stop-motion animated short film produced by Aardman Animations. The film was directed by Nick Park and co-written by Park, Bob Baker, and Brian Sibley. It is the second installment in the Wallace & Gromit series following A Grand Day Out (1989). In the film, Wallace (Peter Sallis) and Gromit find themselves in the crosshairs of a villainous penguin, Feathers McGraw, who uses Wallace's latest invention, a pair of robotic tros, to steal a diamond from the city museum.

Production on The Wrong Tros began 1990. Baker, who was a writer on Doctor Who, took ideas from Park's sketchbooks, suggesting they make a drawing of a penguin the villain. Park wanted to include a chase on a model railway, feeling it would be funny to stage a Hollywood-style action sequence in a living room, so Baker suggested they make a heist film with the train as the denouement.

The Wrong Tros debuted in the UK on 26 December 1993 on BBC Two. Like the previous film, it received critical acclaim. It won the Academy Award for Best Animated Short Film in 1994. The character, Feathers McGraw, returned in the feature-length sixth installment in the series, Vengeance Most Fowl, in 2024.
