"Heart Vacancy" is a song by British-Irish boy band the Wanted from their self-titled debut album.

The song was written by Jonas Jeberg, Cutfather, Lucas Secon, and Wayne Hector.

"Heart Vacancy" was originally written for English singer Leona Lewis, and was given to four different artists before being recorded by the Wanted.

Robert Copsey of Digital Spy gave the song three out of five stars and described it as "a slushy, string-laden slowie about longing for a girl, but with the BPM turned up a notch and a stomping rhythm – too fast for waving lighters but slow enough for hands-in-the-air time – 'Heart Vacancy' treads on the slightly more manly side of sentimental.

"[2] "Heart Vacancy" debuted at number two on the UK Singles Chart with first-week sales of 66,394, second only to the Bruno Mars song "Just the Way You Are".
