Walking is a 1968 Canadian animated short film directed and produced by Ryan Larkin for the National Film Board of Canada, composed of animated vignettes of how different people walk. Following Larkin's work on In the Labyrinth for Expo 67, Larkin submitted a proposal to the NFB for a short film based on sketches of people walking. It took him two years to make the film—twice as long as expected—as he was perfecting new ink wash painting techniques in order to not repeat his earlier films.
