Frank Chamizo Marquez (born 10 July 1992) is a naturalized Italian two-time world freestyle wrestling champion. In all, he has won three world-level medals for Italy, and one for his native Cuba.
Chamizo had a trying childhood. He grew up in poverty, and was raised by his grandmother because both of his parents lived abroad. He began wrestling at the age of seven after walking into a wrestling facility out of curiosity. The Cuban government eventually recognized his talent, and helped him attend a secondary school where he could continue wrestling.
In 2010, Chamizo won a world bronze medal for Cuba. He was only 18 at the time. The next year, in 2011, he returned to the world championships, where he placed twelfth. After the 2011 World Wrestling Championships, however, Cuba's wrestling federation suspended him for two years for alleged difficulties with weight management. At a crossroads in life, he chose to move to Italy, where his ex-wife is from.
