The 2021 WTA German Open (also known as the bett1open for sponsorship purposes) was a professional tennis tournament played on outdoor grass courts at the Rot-Weiss Tennis Club in Berlin, Germany from 14 June to 21 June 2021. It was the 94th edition of the event on the 2021 WTA Tour and was classified as a WTA 500 tournament.[1]
The 2021 relaunch of the German Open marked the first time the WTA Tour returned to Berlin since 2008 after the Qatar Tennis Federation, owners of the original clay tournament usually held prior to the French Open, had sold the sanction back to the Tour.[2] In 2019, the WTA and All England Lawn Tennis and Croquet Club (AELTC) announced that the WTA Premier (now WTA 500) sanction from the Birmingham Classic would be transferred to a new grass tournament planned to be organized in Berlin.[3] Originally scheduled for a debut in 2020, the inaugural edition was postponed to 2021 due to the COVID-19 pandemic in Germany.[4]
Liudmila Samsonova became the relaunched tournament's debut singles champion after entering the main draw as a qualifier and defeating Belinda Bencic in her maiden WTA Tour career final. The all-Belarusian doubles team of Victoria Azarenka and Aryna Sabalenka defeated Nicole Melichar and Demi Schuurs in the final to win the new event's first doubles tournament.[5]
