Antonio Ayala Jr. (February 13, 1963 – May 12, 2015) was an American professional boxer who competed in the light middleweight division.

On January 1, 1983, Ayala broke into his neighbour's house and sexually assaulted her. Despite being 19 years old at the time, he had already been convicted and given probation for two violent attacks on women and was sentenced to 35 years in prison. He was paroled in 1999.

In 2004 he was jailed again for possession of heroin and driving without a license, therefore violating his probation.

Ayala died on May 12, 2015, age 52, from an apparent overdose at Zarzamora Street Gym, San Antonio, Texas. It has been reported in the media that drug paraphernalia was found near his body.
