2021 Birmingham Classic – Singles

Ons Jabeur defeated Daria Kasatkina in the final, 7–5, 6–4, to win the singles tennis title at the 2021 Birmingham Classic. By winning her first career singles title on her third attempt, Jabeur became the first Tunisian and Arab woman to win a singles title on the WTA Tour.
