"Pacific Ocean Blues" is a song written by Dennis Wilson and his cousin Mike Love. The title track, it was released as the ninth track on Dennis Wilson's 1977 debut solo album Pacific Ocean Blue. The track, as with the rest of the album, was credited as being produced by Dennis Wilson and his close friend Gregg Jakobson. Dennis Wilson sings the lead vocals on this and every other track on the album.
A backing track was reportedly recorded by late 1975 and was Dennis Wilson's only submission for The Beach Boys 1976 album 15 Big Ones, though it was turned down by the band. The completed version, although a hard rocker, features unique but inventive water sound effects. Dennis has been quoted as calling the song "my least favorite cut" on the album as he reportedly felt that the song sounded incomplete.
