"The Hardest Part Is the Night" is a single by American rock band Bon Jovi. It is taken from their second album, 7800° Fahrenheit. It is notable for being the first Bon Jovi single to be released in the UK, where it charted at #68. It was the only single from the album not to chart in the U.S.

Among Bon Jovi's early songs, "The Hardest Part is the Night" is the one that expresses most clearly Jon Bon Jovi's concerns with working class issues and the struggles of the underdog, a theme that would later bring success to the band with Livin' on a Prayer. The song makes vague references to a young man battling against the odds to succeed in life, though he knows that he is ultimately "going down".
