2023 National Bank Open – Women's Singles

It was her second WTA 1000 title. Due to rain, Samsonova had to play two matches (third round and quarterfinals) on Friday and two matches again (semifinals and final) on Sunday; she only had a two-hour break between the semifinal and final match. Pegula, on the other hand, played one match each day of the tournament from Wednesday through Sunday.^{[citation needed]}

Simona Halep was the reigning champion, but could not defend her title due to a provisional suspension for violations of anti-doping rules.

Iga Świątek and Aryna Sabalenka were in contention for the WTA No. 1 ranking. Świątek retained the top ranking by reaching the quarterfinals.

This tournament marked the return to professional competition of former No. 1 player Caroline Wozniacki, who previously retired from the sport in 2020. She lost to reigning Wimbledon champion Markéta Vondroušová in the second round.

The top eight seeds received a bye into the second round.
