Michael Carroll (born 29 March 1983 in Swaffham, Norfolk) is an English winner of the UK National Lottery.
A former binman, Carroll won £9,736,131 (then US$15.4m) on the National Lottery in November 2002, aged 19.
He enjoyed a celebrity status for a time in the British media as the self-proclaimed 'King of Chavs', a phrase that he emblazoned on his black Mercedes van. He spent his multi-million fortune on illegal drugs, gambling and prostitutes over the next few years before declaring bankruptcy and returning to the £42 a week in jobseeker's allowance he had been claiming before.
He has since made two suicide attempts.
