"The Chipmunk Song (Christmas Don't Be Late)" is a novelty Christmas song written by Ross Bagdasarian (under the stage name of David Seville) in 1958. Bagdasarian sang and recorded the song, varying the tape speeds to produce high-pitched "chipmunk" voices, with the vocals credited to Alvin and the Chipmunks, Seville's cartoon virtual band. The song won three Grammy Awards in 1958, for Best Comedy Performance, Best Children's Recording, and Best Engineered Record (non-classical); it was also nominated for Record of the Year.

A novelty song is a type of song built upon some form of novel concept, such as a gimmick, a piece of humor, or a sample of popular culture. Novelty songs partially overlap with comedy songs, which are more explicitly based on humor, and with musical parody, especially when the novel gimmick is another popular song. Novelty songs achieved great popularity during the 1920s and 1930s. They had a resurgence of interest in the 1950s and 1960s. The term arose in Tin Pan Alley to describe one of the major divisions of popular music; the other two divisions were ballads and dance music. Humorous songs, or those containing humorous elements, are not necessarily novelty songs.
