The winner, who cannot be named for legal reasons, was sentenced to seven years in jail for the violent attack, after being convicted of rape, witness intimidation and perverting the course of justice.
He has also been convicted of wounding with intent in the mid 1980s, stabbing a neighbour with a knife.
The convicted criminal served four years of his sentence after raping the teenage girl in Milton Keynes, Buckinghamshire, in 1992.
It is understood the man asked for no publicity following his lottery win in 2009.
The disclosure raises the possibility that his victim may be entitled to claim part of his winnings.
