"All My Love" is the penultimate song on English rock band Led Zeppelin's 1979 album, In Through the Out Door. Written by Robert Plant and John Paul Jones, it features a synthesizer solo by Jones. Plant wrote the song as a tribute to his son, Karac, who died from a stomach infection in 1977 at the age of five. Plant did the vocals all in one take, and the song changes key on the last chorus.

All My Love" is one of only two Led Zeppelin songs which Jimmy Page had no part in writing (the other being "South Bound Saurez", also from In Through the Out Door). In an interview he gave to Guitar World magazine in 1998, Page stated that he and John Bonham

...both felt that In Through the Out Door was a little soft. I wasn't really keen on "All My Love". I was a little worried about the chorus. I could just imagine people doing the wave and all of that. And I thought, that's not us. That's not us. In its place it was fine, but I wouldn't have wanted to pursue that direction in the future.^[1]

At approximately 2:50, during John Paul Jones's synth solo, he hits two notes at the same time on accident. Some argue that this was intentional, meant to be a dissonant.

A studio outtake of an extended "All My Love" exists, timed at 7:02 minutes. It has a complete ending, with Plant extending the last verse and a twangy B-Bender guitar solo by Page.^[2] This version has been made available on a number of Led Zeppelin bootleg recordings.

The song was played live on Led Zeppelin's concert tour of Europe in 1980, being the only untried number to be inserted into the tour.^[2] It was one of the most well received performances of the tour. It is also included on the Led Zeppelin compilations Early Days and Latter Days, Remasters and Mothership.

Led Zeppelin parody cover band Dread Zeppelin recorded a version of this song on their album Hot & Spicy Beanburger.

The alternative rock band Ween also covered this song live, on their DVD Ween: Live in Chicago.
