Julio César Chávez Carrasco (born February 16, 1986), best known as Julio César Chávez Jr., is a Mexican professional boxer who held the WBC middleweight title from 2011 to 2012. He is the son of retired six-time world boxing champion Julio César Chávez and older brother of Omar Chávez.
Chávez Jr. was born in the state of Sinaloa, when his father held the WBC World Championship at super featherweight. His face became known to boxing fans when his father would take him and his brother Omar into the ring as children, before each of Chávez Sr.'s fights. As a teenager, Chávez Jr. endured some difficult moments, including a publicized relationship between his father and actress Salma Hayek and the consequential divorce of his parents. Chávez Jr. lived in relative obscurity until he announced that he would follow in the footsteps of his father and become a boxer.
Chávez's amateur career consisted of only two fights against former world champion Jorge Páez's oldest son Jorge Páez Jr.; both of the exhibitions bouts were shown on Mexican television.
