Hector Camacho Jr. was born and raised in New York City. His parents were quite young and did not marry; his father was Héctor Camacho, then 16 years old, who lived in Spanish Harlem. The senior Camacho, nicknamed "Macho", became an amateur boxer and, later a professional.

The boy was nicknamed "Machito". He grew up admiring his father's fighting skills and imitating him, and was more interested in fighting than school. At the age of eight, Camacho Jr. was noted for doing mock sparring with his dad before his father's world title defense on June 13, 1986, against Edwin Rosario at Madison Square Garden in New York City. That night, the boy wore a Puerto Rican flag outfit.

His fight against the former world champion Jesse James Leija resulted in a no contest, after Leija's team protested the awarding of the fight on points to Camacho. The fight was stopped in the fifth round due to an unintentional headbutt by Leija that opened a cut over Camacho's eye. Camacho indicated he did not want to continue. The referees went to their scorecards to determine the winner, and gave Camacho the decision. Many fans felt he quit in the fight.^{[citation needed]}

Camacho is a member of Team Fight to Walk, which raises money to support spinal cord research. Other boxers, including Boyd Melson, Demetrius Andrade, Shawn Estrada, Steve Cunningham and Deandre Latimore, help support this organization.

In 2002, Camacho lost for the first time, to Omar Weis from Argentina, by a decision in ten rounds.

On July 9, 2005, Camacho Jr. and his father co-starred an undercard in Tucson, Arizona.

In July 2007, Camacho lost a decision to Don Juan Futrell. Camacho came in overweight at 161 pounds and was outworked by the 150-pound Futrell. Sports journalists thought Camacho's hopes for any future title contention were in doubt based on his condition and performance in that fight.^[2]

In 2013, Camacho said in an interview that it was his father's death and his conversion to Islam that helped him make his comeback into boxing.^[8] On September 1, 2014, a book written by Camacho, Jr. was published. The book, "Macho Dad", is a comic book that portrays his dad as a Puerto Rican flag-wearing superhero.^[9]
