Elvis Sings The Wonderful World of Christmas is the fifteenth studio album by American singer Elvis Presley, released in October 1971. It was his first Christmas album with new recordings since Elvis' Christmas Album (1957). The album's single, "Merry Christmas Baby" / "O Come All Ye Faithful", was later released in November 1971. This album was a top seller and topped the Billboard Holiday Albums Chart, and would have charted high on the Billboard 200 but from 1963 to 1973, holiday albums were not allowed to chart. It did not have the commercial appeal of Elvis' first Christmas album, but over the years, it has become a perennial favorite. It was certified Gold on November 4, 1977, Platinum on December 1, 1977, 2× Platinum on May 20, 1988, and 3× Platinum on July 15, 1999, by the RIAA.

Several of the songs on the album were published by Elvis Presley's publishing company, such as "Holly Leaves and Christmas Trees", "I'll Be Home on Christmas Day", "If I Get Home on Christmas Day", and "On a Snowy Christmas Night". Presley is accompanied on most of the songs by The Imperials Quartet.
