"Long As I Can See the Light" is a song by American rock band Creedence Clearwater Revival, from the album Cosmo's Factory. It was released as the B-side of the single "Lookin' Out My Back Door" in 1970. While released as a B-side, "Long As I Can See the Light" reached number 57 on the Cash Box singles chart in the US, number 20 in the UK and number one in Norway. In the UK, "Long As I Can See the Light" was placed on the A-side of the single, with "Lookin' Out My Back Door" on the flipside. The two songs were also released as a double-sided single and peaked at number two in the US. On the recorded version, John Fogerty plays electric piano and a sax solo. "Long As I Can See the Light" was included on practically every Creedence Clearwater Revival compilation album (notable examples are The Best of Creedence Clearwater Revival and Chronicle: The 20 Greatest Hits). While never played live by CCR, the song became a concert staple for John Fogerty as a solo artist.

John Fogerty biographer Thomas M. Kitts describes the song as depicting a "world-weary figure," perhaps Jeremiah, who "undertakes an uncertain journey." The singer is confident as long as he "can see the light." Kitts points out that the word light has two meanings in the song, a spiritual meaning, such as in "The Lord is my light" from Psalm 27, and "the secular light of love." Kitts describes the music as having a "hymnal, church-like feel."

John Fogerty expressed surprise in his coming up with a candle as a metaphor for a beacon guiding the singer home. He stated that the song is "about the loner in me. Wanting to feel understood, needing those at home to shine a light so that I can make my way back."
