Svetlana Kuznetsova defeated Agnieszka Radwańska in the final, 6–2, 6–4 to win the women's singles tennis title at the 2009 China Open. It was her second China Open title.^[1]

Jelena Janković was the defending champion, but lost in the second round against Peng Shuai.

This tournament saw world No. 226 Zhang Shuai defeat then-world No. 1 Dinara Safina in the second round, and as such become the lowest-ranked player to ever defeat a reigning world No. 1.^[2] Serena Williams replaced Safina as world No. 1 following the tournament by virtue of winning her second round match, though Williams herself would lose in the third round.^[3]

The four Tokyo semifinalists received a bye into the second round. They are as follows:

• Maria Sharapova (third round)
• Agnieszka Radwańska (final)
• Li Na (third round)
• Jelena Janković (second round)
