"Edge of a Broken Heart" is a power ballad by the American glam metal band Vixen, that was released as a single in 1988. It was written by Richard Marx, who was also on keyboards, and Fee Waybill. The song peaked at No. 26 on the Billboard Hot 100, and although the band had another top 40 hit on that chart, "Cryin'", they are often cited as a one-hit wonder, with this song "being their one hit". According to Marx's memoir Stories to Tell, Michael Landau, not the band's Jan Kuehnemund, played lead guitar on this song.
