2024 US Open – Women's singles

Aryna Sabalenka defeated Jessica Pegula in the final, 7–5, 7–5 to win the women's singles tennis title at the 2024 US Open. It was her first US Open singles title and third major singles title overall. Sabalenka was the fifth woman to win both hardcourt majors in the same year (having also won the Australian Open) since the feat became achievable in 1988, after Steffi Graf, Monica Seles, Martina Hingis and Angelique Kerber. The final was a rematch of the Cincinnati final three weeks earlier, in which Sabalenka also prevailed.

Coco Gauff was the defending champion, but lost in the fourth round to Emma Navarro.

This edition of the US Open had two of the three latest finishes in the history of the tournament. The third-round match between Sabalenka and Ekaterina Alexandrova (which also set the record for the latest start in the history of the tournament beginning at 12:08 AM) was tied for the third-latest finish for a women's singles match at 1:48 AM. The fourth round match between Zheng Qinwen and Donna Vekić set the new record for the latest finish at 2:15 AM.
