Building a Building is a 1933 American animated short film produced by Walt Disney Production and released by United Artists. A remake of the 1928 Oswald the Lucky Rabbit film Sky Scrappers, the cartoon depicts Mickey Mouse working at a construction site under the supervision of Peg-Leg Pete while Minnie Mouse is selling box lunches to the workers. It was directed by David Hand, his first directorial assignment at Disney, and features the voices of Walt Disney as Mickey, Marcellite Garner as Minnie, and Pinto Colvig as Pete. It was the 51st Mickey Mouse short film, and the first of that year.

The film was nominated for the Academy Award for Best Animated Short Film at the 6th Academy Awards, but lost to Disney's own Three Little Pigs. This was the second Mickey Mouse cartoon nominated for an Oscar.
