Elvis Sings The Wonderful World of Christmas is the fifteenth studio album and second Christmas album by American singer Elvis Presley, released by RCA Records in October 1971. It was Presley's first collection of new Christmas recordings since Elvis' Christmas Album (1957). Two songs from the album, "Merry Christmas Baby" and "O Come All Ye Faithful", were issued as a single in November. The album topped the Christmas LP's chart that year and would have charted high on the Billboard Top LPs chart, but from 1963 to 1973, holiday albums were not allowed to chart.
