The Year of the Mouse is a 1965 animated action comedy film featuring Tom and Jerry. It was directed and produced by Chuck Jones, with a story by Jones and Michael Maltese and animation by Dick Thompson, Ben Washam, Ken Harris, and Don Towsley.

In this film, Jerry Mouse and his fellow mouse Nipper torment a sleeping Tom Cat. They repeatedly attack him in his sleep, but Tom is left with the impression that these are incidents of self-harm. The attacks escalate in seriousness. Starting with a fly swatter, the mice proceed to use a revolver, a hangman's noose, a seemingly bloody knife, and a bow and arrow. Tom is increasingly scared, until he notices the mice spying on him. He takes revenge by tormenting them.
