Sandra Graf (born 9 December 1969) is a Swiss wheelchair athlete. Graf competes in wheelchair races of a variety of distances. She has twice put her career on hold to have children. In 2003 a lung embolism set back her training and kept her from competing in the marathon and 5000 meter distances, although she still competed in the 800 and 1500 meter races. In 2008, during her first London Marathon wheelchair race, she both won the race over American Amanda McGrory and Briton Shelly Woods and set a new course record of 1:48:04. She has competed in athletics at the Summer Paralympics three times, from 2000 to 2008, and won a bronze medal in the marathon at the 2008 Beijing Games.
