Alejandro Fabián Hernando (born May 5, 1976) is an Argentine taekwondo practitioner, who competed in the men's featherweight category.
He captured a bronze medal in the 68-kg division at the 1999 Pan American Games in Winnipeg, Manitoba, Canada, and represented his nation Argentina in two editions of the Olympic Games (2000 and 2004).Hernando made his official debut at the 2000 Summer Olympics in Sydney, where he competed in the men's featherweight class (68 kg).
Unlike his previous Olympics, Hernando failed to edge past the opening round after he was narrowly beaten by Danish neophyte Jesper Roesen at 10–11.
With his opponent losing the next bout to South Korea's Song Myeong-seob, Hernando denied his chance to slip into the repechage bracket for the Olympic bronze medal.
