"The Ocean" is a song by English rock band Led Zeppelin, from their 1973 album Houses of the Holy.

The ocean is a metaphor for the "sea of heads" faced by lead singer Robert Plant "in the auditoriums", according to the group's biographer Dave Lewis.

[8] In the last line, the "girl who won my heart" refers to Robert Plant's daughter Carmen, (born 21 November 1968), who was three years old at the time of recording.

In concert, Plant always updated the lyric to reflect her current age, as captured on the Led Zeppelin DVD which features a performance of the song at Madison Square Garden in 1973.

[11] Fletcher further wrote, "Jimmy Page's guitar spits jagged fireballs with John Paul Jones and John Bonham riffing along behind him, but the effect is destroyed by ridiculous backup cooings and an overbearing "killer" coda that's so blatant it can only be taken as a mock of straight rock & roll.
