"Vulnerable" is a song by Swedish pop music duo Roxette, released as the fifth and final single from their fifth studio album Crash! Boom! Bang!, while simultaneously acting as the lead single from the duo's 1995 compilation album Rarities.

"The Sweet Hello, the Sad Goodbye" had previously been released as the B-side on the duo's 1991 single "Spending My Time". Earlier that year, in April, it had been released as the lead single from Thomas Anders' (of Modern Talking fame) second solo album, Whispers.

The song was written by Per Gessle in December 1990, although it would not be recorded by the band until April 1993 at Mayfair Studios in London. In the liner notes of their 1995 greatest hits compilation Don't Bore Us, Get to the Chorus!, Gessle indicated that the song was "written a week too late for the Joyride album and it didn't really suit the Tourism sessions, so we kept it in the drawer until we started the Crash!-project in London."

According to Ultimate Guitar, the track is an alternative pop ballad, with a moderate tempo of 134 beats per minute. The verse is composed of two repetitions of an E–G♯m–A–F♯m–B sequence, with the final note amended to a C♯ on the second repetition. The chorus consists of three repetitions of a F♯–F♯maj7–B–C♯ sequence, followed by one shortened bar of F♯–C♯–F♯.
