2023 Miami Open – Women's singles


Petra Kvitová defeated Elena Rybakina in the final, 7–6, 6–2 to win the women's singles tennis title at the 2023 Miami Open. It was Kvitová's first WTA 1000 title since the 2018 Madrid Open, and her 30th career title overall; she also became the first Czech player to win the title. Rybakina was attempting to complete the Sunshine Double, having already won the title at Indian Wells.
Iga Świątek was the reigning champion, but withdrew before the tournament began due to injury. This was the second consecutive year that the reigning champion pulled out from the tournament, following Ashleigh Barty's retirement from the sport last year.
