The tournament was due to begin at Roland Garros in Paris on May 18 but the French Tennis Federation (FFT) decided to delay the tennis major, which will now run between September 20 and October 4.
“We are acting responsibly, and must work together in the fight to ensure everybody’s health and safety.”
The French Open is usually the second grand slam of the tennis calendar, with the clay-court spectacle running between the Australian Open and Wimbledon.
The new schedule means it will now be the final major of the year, following shortly after the US Open.
Spain’s Rafael Nadal and Australia’s Ashleigh Barty are the respective defending French Open men’s and women’s singles champions.
Organizers have confirmed that any tickets already bought can be refunded or exchanged to take into account the new dates.
Both the ATP and WTA tours have already been temporarily suspended as the world struggles to get to grips with the spread of COVID-19.
