"Shake Up Christmas" is a song by the American rock band Train. It was released on November 1, 2010, as the fourth single from their fifth studio album, Save Me, San Francisco (2009). A different version of the song appears on the band's 2015 Christmas album, Christmas in Tahoe. The song was written by Butch Walker and Pat Monahan.
A music video to accompany the release of "Shake Up Christmas" was first released onto YouTube on November 29, 2010, at a total length of four minutes and one second.
The song features Coca-Cola's jingle of the period, most prominently at the beginning, while the video shows Santa Claus drinking Coca-Cola and shaking a snow globe. Clips from the video were spliced into Christmas Coke commercials during December 2010.
