"Sail On, Sailor" (mislabeled "Sail On Sailor" on original pressings) is a song by American rock band the Beach Boys from their 1973 album Holland. It was written primarily by Van Dyke Parks and Brian Wilson with Ray Kennedy, Tandyn Almer, and Jack Rieley. The lead singer on the song is Blondie Chaplin, making this one of the band's few well-known songs not sung by Mike Love, Brian Wilson, or Carl Wilson. The song was released as a single in 1973, backed with "Only with You", and peaked at number 79 on the American singles charts. A 1975 reissue (also backed with "Only with You") charted higher, at number 49.

Wilson himself later stated, "It's the only song that we did that I absolutely do not like at all. I never liked 'Sail On, Sailor'." Nonetheless, according to biographer Jon Stebbins, the song "is perhaps the only perennial Beach Boys favorite to still thrive in the classic rock and album rock FM radio formats of the present."
