2023 US Open – Women's singles

Coco Gauff defeated Aryna Sabalenka in the final, 2–6, 6–3, 6–2 to win the women's singles tennis title at the 2023 US Open. It was her first major title. Gauff became the first American teenager to win the title since Serena Williams in 1999, and one of three teenagers to win the title within five years, following Bianca Andreescu in 2019 and Emma Raducanu in 2021. Sabalenka became the first woman since Serena Williams in 2016 to reach at least the semifinals of all four majors in a season.

Iga Świątek was the defending champion, but lost to Jeļena Ostapenko in the fourth round. Her defeat guaranteed a first-time US Open champion. Świątek and Sabalenka were in contention for the world No. 1 ranking. As a result of Świątek's fourth-round loss, Sabalenka claimed the top ranking for the first time in her career.

The third round match between Caroline Wozniacki, ranked No. 623, and Jennifer Brady, ranked No. 433, who were both playing their first majors in more than two years, was the first third round match in any major between two players outside the top 300 in singles rankings, male or female.

This was the first major since 2019 US Open in which all eight of the quarterfinalists were seeded. Sorana Cîrstea made her first US Open quarterfinal on her 15th attempt, an Open Era record shared with Nathalie Tauziat. Cîrstea reached her second major quarterfinal 14 years after her first at the 2009 French Open, second only to Mirjana Lučić-Baroni's near 18-year gap between major quarterfinal appearances.
