"I Wish It Could Be Christmas Every Day" is a Christmas song recorded by British glam rock band Wizzard. It was first released in December 1973 and, as with most Wizzard songs, was written and produced by the band's frontman Roy Wood—formerly of The Move and a founding member of Electric Light Orchestra. Despite the song's strong, long-lasting popularity, it has reached no higher than number four on the UK Singles Chart, a position it occupied for four consecutive weeks from December 1973 to January 1974. The song was beaten to the 1973 Christmas Number 1 spot by Slade's "Merry Xmas Everybody", which remained at the top of the charts for five weeks, from December 1973 to January 1974.

Christmas music comprises a variety of genres of music regularly performed or heard around the Christmas season. Music associated with Christmas may be purely instrumental, or, in the case of carols, may employ lyrics about the nativity of Jesus Christ, traditions such as gift-giving and merrymaking, cultural figures such as Santa Claus, or other topics. Many songs simply have a winter or seasonal theme, or have been adopted into the canon for other reasons.
