Which Disney Pooh short won an Academy Award for Best Animated Short?

The Disney Pooh short that won an Academy Award for Best Animated Short was Winnie the Pooh and the Blustery Day.

Released in 1968, the animated featurette was produced by Walt Disney Productions and directed by Wolfgang Reitherman. It adapts episodes from both Winnie-the-Pooh and The House at Pooh Corner, A. A. Milne’s two principal Pooh story collections.

The film follows Pooh and his friends through windy weather, flooding and other comic troubles. Its 25-minute running time places it between a conventional theatrical cartoon and a feature film. It was released with The Horse in the Gray Flannel Suit, a live-action Disney film.

The award is sometimes described using its older category name, Best Short Subject (Cartoon), rather than Best Animated Short Film. The film won for the 1968 movie year at the 41st Academy Awards, held in 1969. The award was credited to Walt Disney posthumously, following his death in 1966. Winnie the Pooh and the Honey Tree was an earlier Pooh short but did not win this Oscar.
