"Happy Holiday" (sometimes performed as "Happy Holidays") is a popular song composed by Irving Berlin during 1942 and published the following year.
"Happy Holiday" was introduced by Bing Crosby in the 1942 film Holiday Inn, with The Music Maid and Hal and John Scott Trotter and His Orchestra, where it is performed in a medley with the title song. While it is commonly regarded as a Christmas song, in the film it is performed on New Year's Eve, and expresses a wish for the listener to enjoy "happy holidays" throughout the entire year.
The song helped to popularize the phrase "Happy holidays" as a common greeting during the Christmas and holiday season in the United States.
Kay Thompson wrote a song called "The Holiday Season" which is sometimes paired with "Happy Holiday" as a medley. This was first popularized by Andy Williams (who Thompson herself discovered and mentored). Other artists who have covered the "Happy Holiday"/"Holiday Season" medley include The Manhattan Transfer, She & Him, and Michael W. Smith.
