Updated on July 20 to reflect withdrawals.

Warsaw is one of three WTA 250 events taking place the week of July 24, along with the Hamburg European Open and Ladies Open Lausanne. 

Daria Kasatkina and Donna Vekic lead the field in Hamburg, where Bernarda Pera will return to defend her title. Belinda Bencic was initially entered to be the top seed at her home event in Lausanne, but withdrew due to shoulder injury. Romania's Irina Camelia Begu is now the top seed. Teen phenom Mirra Andreeva is also entered to play. Both tournaments are played on outdoor clay.
