British number one Laura Robson will play former world number one Caroline Wozniacki in the first round of the French Open.
Danish 10th seed Wozniacki comes into the tournament on the back of four consecutive losses on clay.
British number two Heather Watson will play Stefanie Voegele, while Elena Baltacha takes on Marina Erakovic.
Andy Murray's absence through injury
means there are no Britons in the men's singles for the first time since 1994.
Laura Robson in detail
- Age: 19
- Current ranking: 35 (career-high)
- She is the 2012 Olympic silver medallist in mixed doubles with Andy Murray.
- She became the first British woman for 22 years to reach a WTA singles final in Guangzhou in September 2012.
- She has suffered six first-round defeats in 2013.
- She reached the fourth round of the US Open in 2012 and the third round of the 2013 Australian Open.
- She has beaten four former Grand Slam singles champions so far in her career - Kim Clijsters, Li Na, Petra Kvitova and Venus Williams.
- She achieved her first victory over a player ranked inside the world's top five, beating world number four Agnieska Radwanska at the Madrid Open in May 2013.
- She reached her first WTA doubles final with Lisa Raymond in Miami in March 2013.
going for an eighth French Open title,
is seeded third and could meet world number one Novak Djokovic in the semi-finals after they were drawn in the same half.
The Spaniard plays Germany's Daniel Brands first, while Djokovic is up against Belgian David Goffin. Second seed Roger Federer takes on a qualifier.
"If we're not one and two in the world, that can happen," said Nadal. "But the tournament starts from the first round and I'm sure that both of us know that we have a hard way before that."
The French Open remains the only Grand Slam Djokovic has not won and the 26-year-old said: "This is the tournament that is the number one priority of my year, of my season.
"This is where I want to win and I'm going to go for it. I think my game is there and I'm very, very motivated."
In the women's draw, top seed Serena Williams will hope to avoid
last year's shock first-round loss to Virginie Razzano
when she plays Georgia's Anna Tatishvili. The American won her only Roland Garros title in 2002.
Asked if she was playing as well as she ever has, Williams, who is on a personal-best winning streak of 24 matches, said: "I think so.
"Just looking back at a few of my matches years ago and looking now, I definitely feel like I'm getting into that zone that I have always wanted to be in."
Defending champion Maria Sharapova begins against Su-Wei Hsieh of Chinese Taipei.
The tournament begins on Sunday, with the order of play yet to be announced and the first round split across three days.
Wozniacki won't fancy this one little bit. She's going through a horrendous run of bad form, losing four matches in a row on the European clay, and she's well aware of Robson's recent high-profile scalps.
Laura's been hitting well in practice and has a great shot of another upset. In her coaching corner will be Iain Bates, from the LTA's Fed Cup team, as Sven Groenveld - her interim coach - has to remain impartial. He works for Adidas and is also close to Wozniacki, another client of the clothing manufacturer.
Robson enters the tournament at a career-high ranking of 35 and with a
growing list of notable scalps to her name.
However, she has also shown a vulnerability against lower-ranked players in recent months and struggled with her serve, leading to
a split with coach Zelko Krajan this month.
The 19-year-old has admitted she finds it easier to play well against the bigger names, and an out-of-form Wozniacki could prove to be an ideal opponent, with the pair preparing to meet for the first time.
Watson, 21, remains 50th in the rankings despite
having not played for two months because of glandular fever,
and will look to defend the ranking points earned by reaching round two last year.
She has a 1-1 record against Swiss world number 58 Voegele, having beaten her in Paris two years ago but lost in Memphis earlier this year.
Baltacha returns to Grand Slam action for the first time since Wimbledon,
following an ankle injury
that she has admitted almost ended her career and has seen her slip to 234 in the world.
The Scot, 29, makes the main draw at Roland Garros with a protected ranking given to players who miss a substantial time through injury.
