"Love Bites" is a song by English glam metal band Def Leppard from their album Hysteria.

The power ballad[1][2] is Def Leppard's only number-one single on the US Billboard Hot 100 and became a top-10 hit in Canada, Ireland, and New Zealand.

[3] The title "Love Bites" was originally used for a very different song that was eventually re-titled "I Wanna Be Your Hero", and which appeared as a Hysteria B-side and later on the album Retro Active.

[2] Following the huge momentum generated by "Pour Some Sugar on Me", the song was released in August 1988 and peaked atop the US Billboard Hot 100 for one week.

[8][9][10][11] The "Love Bites" 45 release in Canada and UK included limited edition gatefold with complete "Hysteria" lyrics.
