Chicago XXXVII: Chicago Christmas, also known as simply Chicago Christmas, is the twenty-fifth studio album, the fourth collection of Christmas songs, and thirty-seventh album overall by the American rock band, Chicago. The album was released on October 11, 2019. The project grew out of a plan to record a few new bonus tracks for a re-release of one of the band's prior holiday albums. Unlike previous Christmas albums, Chicago Christmas features primarily original material, written by members of the band. The only non-original songs on the album are "What the World Needs Now Is Love", "Sleigh Ride (2019)", and "Here We Come a Caroling". Chicago Christmas reached number one on the Billboard Holiday Albums Sales Chart.
