Winnie the Pooh and a Day for Eeyore is a 1983 American animated short film based on the sixth chapter of both books Winnie-the-Pooh and The House at Pooh Corner by A.A. Milne. Produced by Walt Disney Productions and distributed by Buena Vista Distribution, the short initially received limited release on May 11, 1983, before expanding to a wide release on May 25 as part of a double feature with the re-issue of The Sword in the Stone (1963), which it accompanied in most countries except Australia where it accompanied a reissue of Bedknobs and Broomsticks (1971). Directed by Rick Reinert, the featurette featured the voices of Hal Smith, John Fiedler, Will Ryan, Ralph Wright, and Paul Winchell.

Additionally, the animation was produced by Rick Reinert Productions, which went uncredited. It would be the first Disney animated film since the 1938 Silly Symphonies short Merbabies to be produced by an outside studio. The company had also previously produced the educational Disney short Winnie the Pooh Discovers the Seasons in 1981.

Winnie the Pooh and a Day for Eeyore was the fourth and final animated featurette in the Winnie the Pooh film series and one of Disney's original theatrical featurettes adapted from the Pooh books by A.A. Milne.
