I Haven't Got a Hat is a 1935 animated short film, directed by Isadore Freleng for Leon Schlesinger Productions as part of the Merrie Melodies series. Released on March 2, 1935, the short is notable for featuring the first appearance of several Warner Bros. cartoon characters, most notably future cartoon star Porky Pig. Beans the Cat, a minor Looney Tunes star in 1935-1936, also made his first appearance in this cartoon.

I Haven't Got a Hat was one of the earliest Technicolor Merrie Melodies, and (because of Walt Disney's exclusive deal with Technicolor at the time) was produced using Technicolor's two-strip process (red and green) instead of its more expensive and advanced three-strip process.
