List of Christmas number one singles

Christmas music comprises a variety of genres of music normally performed or heard around the Christmas season.

Music was an early feature of the Christmas season and its celebrations. The earliest examples are hymnographic works (chants and litanies) intended for liturgical use in observance of both the Feast of the Nativity and Theophany, many of which are still in use by the Eastern Orthodox Church. The 13th century saw the rise of the carol written in the vernacular, under the influence of Francis of Assisi.

In the Middle Ages, the English combined circle dances with singing and called them carols. Later, the word carol came to mean a song in which a religious topic is treated in a style that is familiar or festive. From Italy, it passed to France and Germany, and later to England. Christmas carols in English first appear in a 1426 work of John Audelay, a Shropshire priest and poet, who lists 25 "caroles of Cristemas", probably sung by groups of wassailers, who went from house to house. Music in itself soon became one of the greatest tributes to Christmas, and Christmas music includes some of the noblest compositions of the great musicians.

During the Commonwealth of England government under Cromwell, the Rump Parliament prohibited the practice of singing Christmas carols as Pagan and sinful. Like other customs associated with popular Catholic Christianity, it earned the disapproval of Protestant Puritans. Famously, Cromwell's interregnum prohibited all celebrations of the Christmas holiday. This attempt to ban the public celebration of Christmas can also be seen in the early history of Father Christmas.
