2005 French Open

The 2005 French Open was the 109th edition of the tournament.

On the men's side, Rafael Nadal, seeded fourth at his first French Open, was a strong favorite to win the singles title after winning the Monte Carlo and Rome Masters. Guillermo Coria, the defending finalist and 2005 runner-up to Nadal in both Monaco and Rome, called Nadal the best clay-court player in the world prior to the tournament. After defeating top seed Roger Federer in the semifinals, Nadal defeated Mariano Puerta to claim his first French Open title, and the first of four won consecutively from 2005 until 2008. Nadal would go on to win the tournament a record 14 times.

In the women's draw, Justine Henin-Hardenne won her second French Open title, defeating 2000 champion Mary Pierce in the final in just 62 minutes. 2005 marked the first of three consecutive years in which Henin would win the women's singles title.

Gastón Gaudio and Anastasia Myskina were unsuccessful in defending their 2004 titles, Gaudio losing in the fourth round and Myskina being upset in the first round. This tournament was also notable for the rise of future French Open champion Ana Ivanovic, who upset the third seed Amélie Mauresmo in the third round, before going on to defeat another future champion in Francesca Schiavone on her way to her first major quarterfinal appearance in just her second major tournament.
