Louzanne Coetzee (born 18 April 1993) is a South African para-athlete. Coetzee was born blind as a result of a hereditary condition called Leber congenital amaurosis and competes in the T11 disability class, for athletes with the highest level of visual impairment. In 2018, Coetzee broke the 5000 m (women) world record in her disability class whilst in the same year she became the first visually impaired athlete to compete at the World University Cross Country Championships in Switzerland.
Coetzee competed at the 2016 Summer Paralympics representing South Africa in the Women's 1500 metres. She was, however, disqualified when her guide, Khotatso Mokone, was deemed to have provided illegal assistance.
In 2021, Coetzee competed at the 2020 Tokyo Paralympics, winning the silver medal in the 1500 m final in a new Africa record of 4:40.96 alongside her guide Erasmus Badenhorst, and the bronze medal in the T12 women's marathon, with guide Claus Kempen, in a new T11 world record time of 3:11:13.
Besides running she enjoys baking, watching movies, walking and hiking, cycling and has recently taken up some artistic hobbies as well. She is fun-loving and laughs and talks easily.
