Wallace & Gromit's World of Invention is a British science-themed miniseries, starring Peter Sallis, Ashley Jensen, Jem Stansfield, and John Sparkes, produced by Aardman Animations, which aired on BBC One during 2010, from 3 November to 8 December and Channel 10 during 2011, from 20 September to 6 October. The programme focuses on inventions based around various themes, and consists of live-action films interlaced with animated claymation segments hosted by characters Wallace & Gromit, featuring a side-plot connected to that episode's theme. While Sallis reprises his role as the voice of Wallace, live-action film segments were either narrated by Jensen or presented by Stansfield, with Sparkes providing the voice of unseen archivist Goronwy, a unique character for the programme.

The programme ran for six episodes and was the last production that Sallis performed in before his retirement from acting due to ill health. Its creation was aimed by the BBC at inspiring a new generation of inventors, according to a press statement released prior to the programme's broadcast.
