"Without You" is a song written by Pete Ham and Tom Evans of British rock group Badfinger, and first released on their 1970 album No Dice. The power ballad has been recorded by over 180 artists, and versions released as singles by Harry Nilsson (1971), T. G. Sheppard (1983) and Mariah Carey (1994) became international best-sellers.
The Nilsson version was included in 2021's Rolling Stone's 500 Greatest Songs of All Time. Paul McCartney once described the ballad as "the killer song of all time".
In 1972, writers Ham and Evans received the British Academy's Ivor Novello Award for Best Song Musically and Lyrically.
