Your Friend the Rat is a 2007 American animated short film by Pixar, written and directed by Jim Capobianco. The special takes on the form of an educational film and stars rats Remy and Emile, the main protagonists of Ratatouille, who argue for the reconciliation of humans and rats. They use historical facts presented via various styles of animation in a style similar to the Adventures in Music shorts, Melody and Toot, Whistle, Plunk and Boom.

This is Pixar's only special to feature traditional animation; at eleven minutes, it is also the 3rd longest Pixar special to date. Along with 2D animation, the short also includes stop-motion animation, computer generated imagery (CGI) and live action, much like the children's television show, A Little Curious.

Like Ratatouille, Your Friend the Rat also features a musical sequence. This is also Pixar's only special to have a cameo of a protagonist of a film that would be released a year later, which was a cameo of WALL-E. Your Friend the Rat won the category of Best Animated Short Subject at the 35th Annual Annie Awards.

The short was not released in Japan due to the short containing comedic use of live footage of the Atomic Bomb.
