Williams overcame illness to win her third consecutive Grand Slam at the French Open earlier this month and will hold all four of the game's major women's singles titles if she is able to claim a sixth Wimbledon crown.
The American is in the same half of the draw as 2004 winner Maria Sharapova and could face sister Venus — also a five-time Wimbledon singles champion — in the fourth round.
Sharapova starts the tournament against Britain's Johanna Konta, who impressed in reaching the quarterfinals of this week's Aegon International.
French Open finalist Lucie Safarova is a potential quarterfinal opponent for Sharapova.
Defending champion Petra Kvitova and Simona Halep are the leading seeds in the bottom half of the draw.
Two-time winner Kvitova faces Kiki Bertens first up, while Halep has been handed an opening match against Jana Cepelova.
