The Tallinn Open was a tennis event held in Tallinn, Estonia. The first and only edition took place in October 2022.[1] The event was part of the WTA Tour and is listed as a WTA 250 tournament. The tournament was introduced in 2022 as a result of the cancellation of WTA events in China due to the Peng Shuai sexual assault and disappearance controversy.[2] Estonia's top ranked player Anett Kontaveit played a major role in bringing the event to Estonia, after facing political resistance.[3] In 2023, it was announced that the tournament would no longer be held due to being unable to find financial support and the requirement of allowing athletes from Belarus and Russia to compete.[4]
The tournament was held at the FORUS Tennis Center on indoor hardcourts.
