"Coma" is a song by American rock band Guns N' Roses. It appears on the 1991 album Use Your Illusion I. At 10 minutes, 14 seconds it is the longest track released by the band, even though it lacks choruses.

The song starts with the instruments, and then the singing. After a moderately-sized vocal section, the sound of a heartbeat on a heart monitor takes over, succeeded by another short singing session. Afterwards, more singing takes place, followed by a quiet, peaceful midsection of the song, resembling a euphoric state of tranquility. Then, loud rock music resumes, and a loud, climatic, long singing section finalizes the song.

Slash states that he wrote the music to this song in a house he and Izzy Stradlin rented in Hollywood Hills, following the Appetite for Destruction tours. In a 2011 interview, he stated he wrote the song in a "heroin delirium".

In an interview, Axl Rose talks about writing "Coma":

I tried to write that song for a year, and couldn't. I went to write it at the studio and passed out. I woke up two hours later and sat down and wrote the whole end of the song, like, just off the top of my head. It was like, don't even know what's coming out, man, but it's coming. I think one of the best things that I've ever written was maybe the end segment of the song "Coma". It just poured out.

In an interview, on August 31, 1990, with MTV's Kurt Loder on Famous Last Words, Axl talks about the song "Coma":

There's a song called Coma that's like 11 minutes 45 seconds long with no chorus. And I think there was only one verse that somewhere it repeats itself. It's Slash's baby. It's his monster. The song used to be called Girth.

But I started writing about when I OD'ed 4 years ago. The reason I OD'd was because of stress. I couldn't take it. And I just grabbed the bottle of pills in an argument and just gulped them down and I ended up in the hospital. But I liked that I wasn't in the fight anymore and I was fully conscious that I was leaving. I liked that. But then I go, all of a sudden, my first real thoughts were that "okay, you haven't toured enough. The record's not going to last; it's going to be forgotten. This and that, you have work to do. Get out of this." And I went "No!" and I woke up, you know, and pulled myself out of it.

But in the describing of that, some people could take it wrong and think this means "go put yourself into a coma," you know. And so it's really tricky, and I'm still playing with the words to figure out how to, like, show some hope in there.
