"Olive Tree" is a song by English musician Peter Gabriel, released in August 2023 as the eighth single in promotion of his tenth studio album I/O. Since August had a blue moon in 2023, this was the first of two tracks that was released in August, the other being "Love Can Heal". Three different mixes were released starting with the Bright-Side Mix on 1 August 2023, mixed by Spike Stent. The Dark-Side and In-Side mixes followed later that month, which were mixed by Tchad Blake and Hans-Martin Buff respectively. Gabriel said of the song, "I wanted it to have some speed to it but I also wanted some mystery, too. I think it is a celebration in a way and there's a real sense of being alive."
