2019 French Open

The 2019 French Open was a major tennis tournament played on outdoor clay courts. It was held at the Stade Roland Garros in Paris, France, from 26 May to 9 June, comprising singles, doubles and mixed doubles play. Junior and wheelchair tournaments were also scheduled. Rafael Nadal was the two-time defending champion in men's singles and won his record 12th French Open singles title. Simona Halep was the defending champion in women's singles, but lost in the quarterfinals; the title was won by Ashleigh Barty.

It was the 123rd edition of the French Open and the second Grand Slam event of 2019. The main singles draws included 16 qualifiers for men and 12 for women out of 128 players in each draw. This was in contrast to two other Grand Slam tournaments – the Australian Open and Wimbledon, which from 2019 increased the number of women qualifiers to 16, to match with the US Open.

2019 was the final year in which there was no roof on any of the Roland-Garros tennis courts. On 5 June 2019, the entire day's tennis was washed out due to heavy rain. It is also the only Grand Slam to retain the advantage set in final sets, whereas the Australian Open and Wimbledon have now switched to tiebreaks.
