Joseph Morris Gersten (born July 19, 1947) was an American politician in the state of Florida.
He served in the Florida House of Representatives from 1974 to 1981 (109th district). He also served in the Florida Senate from 1982 to 1986.
In 1993 he fled to Australia after prosecutors wanted to question him about the theft of his baby blue Mercedes-Benz and allegations that it was stolen while he was having sex with a prostitute at a crack house in Miami. In 2001, U.S. Rep. Dan Burton an Indiana Republican, released a report alleging Gersten was the victim of prosecutorial misconduct by Janet Reno, a former Miami-Dade state attorney.
