The Karnival Kid is a 1929 Mickey Mouse short animated film released by Celebrity Productions, as part of the Mickey Mouse film series. It was directed by Walt Disney and animated by Ub Iwerks, with music by Carl W. Stalling. It was the ninth Mickey Mouse short to be produced, the sixth of that year.The short was produced in black and white by The Walt Disney Studio and released to theaters by Celebrity Productions. It is the ninth film in the Mickey Mouse film series, and the first in which Mickey speaks. (During his first eight appearances Mickey whistled, laughed, cried and otherwise vocally expressed himself.) Mickey's first spoken line is "Hot dogs! Hot dogs!", the voice being provided by composer Carl W. Stalling instead of Walt Disney. This would later serve as a basis for Mickey's later catchphrase "Hot dog!"

Three other recurring characters of the series also appear. The first is Clarabelle Cow in a cameo. The second is a carnival barker -- "a direct forerunner, in both looks and behavior, of the later comics character Kat Nipp." The third is Mickey's recurring love interest, Minnie Mouse.

The short will enter the US public domain on January 1, 2025.
