Nicolas Mahut and Vasek Pospisil are the doubles champions of the 2020 Open 13 Provence. The Franco-Canadian team defeated Koolhof/Mektic 6/36/4.
A week after his title in Rotterdam along side Pierre-Hugues Herbert, Nicolas Mahut repeated, this time alongside Vasek Pospisil of Canada. The Frenchman clocked in his 30th title in doubles. In 2016, the only other time the two teamed up was in Rotterdam in 2016 and there also they ended the week with the trophy.
