The 2021 Yarra Valley Classic was a tournament on the 2021 WTA Tour, one of six events in the 2021 Melbourne Summer Series. It was played on outdoor hard courts in Melbourne, Australia. It was organised as a lead-up tournament to the 2021 Australian Open, and was held at the same venue, due to other tournaments in Australia being cancelled as a result from the COVID-19 pandemic. This tournament took place simultaneously with the 2021 Gippsland Trophy and the 2021 Grampians Trophy. Players who had originally intended to participate in this tournament or the Gippsland Trophy, but were forced to undergo strict quarantine measures upon arrival in Australia, were able to participate in the 2021 Grampians Trophy. The entry list of 2021 Australian Open was used to determine the entry list of this tournament; with half the players (selected randomly) playing the Yarra Valley Classic, and the other half playing the 2021 Gippsland Trophy.[1]
In the women's singles final, Ashleigh Barty defeated Garbiñe Muguruza in straight sets, while Shuko Aoyama and Ena Shibahara won in women's doubles.[2]
