Mr. Bug Goes to Town (also known as Hoppity Goes to Town and Bugville) is a 1941 American animated Technicolor feature film produced by Fleischer Studios, previewed by Paramount Pictures on December 4, 1941, and released in California and New York City in February 1942. The film was originally intended to be an adaptation of Maurice Maeterlinck's The Life of the Bee, but Paramount was unwilling to purchase the rights from Samuel Goldwyn, and instead developed an original modern story loosely inspired by the book.

The film was produced by Max Fleischer and directed by Dave Fleischer. It features the songs "We're the Couple in the Castle", "Katy Did, Katy Didn't", "I'll Dance at Your Wedding (Honey Dear)" by Hoagy Carmichael and Frank Loesser, and "Boy Oh Boy" by Sammy Timberg and Loesser. It was Paramount's last animated feature film until Charlotte's Web in 1973.
