The news was made official by organizers of the elite running event on Wednesday.
This year’s Paris Marathon had originally been planned to take place on April 5, but due to the coronavirus pandemic, it was later postponed to November 15.
Eventually, the event was scrapped entirely from this year’s calendar.
"After having tried everything to maintain the event, we, alongside the City of Paris, feel obliged to cancel the 2020 edition of the Schneider Electric Marathon de Paris and the Paris Breakfast Run," organizers said in a statement.
"Faced with the difficulty that many runners, especially those coming from abroad, had in making themselves available... it was decided that it would be better... for those concerned if we organized the Schneider Electric Marathon de Paris in 2021.
"We will be working side-by-side with the City of Paris to put on a 2021 edition that brings together the most passionate runners on the most beautiful streets in the world."
The Paris marathon, one of the most popular events on the global running calendar which routinely attracts over 40,000 participants, is the latest to be disrupted by the worldwide novel coronavirus outbreak.
