Cult of One is the fourth full-length studio album by American thrash metal band Whiplash. It was released on Massacre Records in 1996 and follows a seven-year absence of the band after 1989's Insult to Injury. A different vocalist and bass player, and an additional guitarist joined originals Tony Portaro and Tony Scaglione – a line-up which again changed for the following year's offering, Sit Stand Kneel Prey.
