"All My Love" is the sixth song on Led Zeppelin's 1979 album In Through the Out Door. Credited to Robert Plant and John Paul Jones, it is a rock ballad that features a synthesizer solo by Jones. It was written in honour of Plant's son Karac, who died while Led Zeppelin was on their 1977 North American tour.
"All My Love" is one of only two Led Zeppelin songs that Jimmy Page had no part in writing (the other being "South Bound Saurez", also from In Through the Out Door).
In a review for In Through the Out Door (Deluxe Edition), Andrew Doscas of PopMatters described "All My Love" as "the saddest and most heartfelt Zeppelin song." Doscas described the song as "a fitting ode to Plant's son, which hauntingly enough sounds like a foreshadowing of a band on the path to an impending and unforeseeable dissolution.
In an interview he later gave to rock journalist Cameron Crowe, Plant stated that this song was one of Led Zeppelin's "finest moments". However, guitarist Jimmy Page and drummer John Bonham had reservations about the song's soft rock sound.
