Hells Bells is the first track of the album, Back in Black, of Australian hard rock band AC/DC.

The song starts off with the ominous slow tolling of a bell four times and an intro. After that, it goes for another nine times.

Eventually the bassist Cliff Williams and the drummer Phil Rudd start playing. The lyrics, sung by Brian Johnson, explain how the narrator will attack, comparing his actions with natural phenomena such as rain, thunders and hurricanes.

The song invokes the feeling that the narrator has been sent to drag a soul into Hell. The lines "I got my bell/I'm gonna take you to hell," among others, appear to support this.

The song Hells Bells was written to commemorate the death of AC/DC's lead singer Bon Scott, who was found dead in his car following a night of binge drinking.

Karen and Gar Bell's youngest child, Bon, aged 15 months, was named after Bon Scott.
