"The Littlest Giant" is the 7th episode of the first season of The Ren & Stimpy Show that originally aired on Nickelodeon in the United States on 15 September 1991.

Ren and Stimpy quarrel about what to read before going to bed. Stimpy reads the book The Littlest Giant about a giant cat played by himself who mocked as the smallest giant. After crying his eyes out over his rejection by his fellow giants, Stimpy leaves the land of giants and finds a struggling farmer Wee Ren whom he assists in various ways.

The episode was the last in a short lived series called Stimpy's Storybook Land.^[1] The illustrator Jim Smith drew background scenes based on the work of N. C. Wyeth that gave the story "an appropriate storybook look and feel".^[1] The team who worked on "The Littlest Giant" have panned the writing on the episode with Bob Camp calling it an episode where "you have to wait for them to say what's going to happen before it happens".^[1] The director, John Kricfalusi, had his name removed from the credits in order to disallow his own work.

The journalist Thad Komorowksi wrote that "The Littlest Giant" was one of the worse episodes in the first season that was "a run-of-the-mill Saturday morning cartoon".^[2]
