Ronald Belford Scott (July 91946–February 191980), better known as Bon Scott, was the lead singer and frontman of the Australian hard rock band AC/DC.

He was born in Kirriemuir, Scotland; his family relocated to Australia in 1952.

By 1970 Scott had already enjoyed some limited success in various rock and R&B groups, as a singer and sometimes a drummer as well. In the early 1970s his band Fraternity seemed to be well on its way to fame and fortune. In 1973, just after returning to Adelaide after a touring England, Scott was seriously wounded in a motorcycle accident in which he lost his left testicle. Fraternity continued on without him but never achieved the kind of success Scott would enjoy with his next band.

The following year, while working as a roadie and part-time chauffeur in the local Sydney music scene, that Scott first met the members of AC/DC. The band was driven by the brothers Angus and Malcolm Young, younger siblings of Scott's friend George Young of The EasyBeats. Scott was amazed by the band's energy and drive, and the naive bandmates were, in turn, quite taken with the experienced frontman. When singer Dave Evans got fired from AC/DC a few months later, the band knew who they wanted. Bon Scott joined AC/DC near the end of 1974.

Scott, known for his heavy drinking binges, was found dead in a friend's parked car outside his friend's apartment in south London. He had suffocated on his own vomit although the international press made false accusations about a drug overdose.

Scott is buried in Fremantle Cemetery's Memorial Garden in Australia, the town where he grew up.
