2020 Prague Open

The 2020 Prague Open (branded as the 2020 J&T Banka Prague Open for sponsorship reasons) was a professional women's tennis tournament that was played on outdoor clay courts at the TK Sparta Prague in Prague, Czech Republic. It was a WTA International-class tournament on the 2020 WTA Tour.

The tournament was played from 10 to 16 August 2020, delayed from its usual late-April scheduling due to the COVID-19 pandemic. The tournament was held simultaneously with a second, U.S.-based event, the Top Seed Open in Kentucky, in order to provide additional options for players leading into the 2020 Western & Southern Open in New York City.
