The Olympic 400m hurdles gold medallist at the Los Angeles Games in 1984, El Moutawakel becomes the highest-ranking woman in the Olympic Movement and first female from a Muslim nation to sit on the IOC's rule-making body.
"I feel honoured. I will give my full commitment to the work that is done in this wonderful [Olympic] Family to promote even more our Olympic ideals," said El Moutawakel.
Nawal El Moutawakel stood unopposed for a seat on the 15-member board after Puerto Rico's Richard Carrion and Great Britain's Craig Reedie said they would not contest the seat.
