The 2021 J&T Banka Ostrava Open was a WTA tournament organised for female professional tennis players on indoor hard courts. It was the 2nd edition of the event on the 2021 WTA Tour, primarily organised due to the cancellation of the Asian tournaments during the 2021 season, because of the ongoing COVID-19 pandemic. The event took place at the Ostravar Arena in Ostrava, Czech Republic, from 20 through 26 September 2021.
