"Ana's Song (Open Fire)" was the second single off the band Silverchair's third album, Neon Ballroom.

It was about lead singer Daniel Johns' struggle with anorexia nervosa.

Lyrics from "Ana's Song", particularly the line "I love you to the bones", are sometimes quoted by members of the pro-ana internet subculture.

The song starts in a Ebmaj/B-flat major chord.

The single earned Silverchair a Comet Award in Germany.
