Saúl Mendoza (born January 6, 1967) is a former wheelchair racer, who competed at the Olympic and Paralympic levels.
He acquired polio when he was 6 months old, and he grew up playing different sports.
At the 2000 Olympic Games, he finished first in the demonstration event of Men's 1500m wheelchair. He finished second in the same event at the 2004 Summer Olympics.
He won six medals in different athletics events at the Paralympic Games - 2 gold, 1 silver, and 3 bronze - in a career that spanned from Seoul 1988 to Beijing 2008.
He was the flag-bearer for the Mexican team in the Sydney 2000 and Beijing 2008 Paralympic Games.
The 2008 Paralympic Games were his sixth and final Paralympic appearance, as he had previously announced he would retire from competition after the Games.
However, he returned to the sport to compete in the 2012 London Paralympic marathon on Sunday 9 September having earlier in the season set a new personal best of 1:24:23. 
Mendoza has also won the wheelchair division in the Twin Cities Marathon nine times.
