The 2021 Western & Southern Open was a men's and women's tennis tournament played on outdoor hard courts from August 15–22, 2021, as part of the US Open Series. It was a Masters 1000 tournament on the 2021 ATP Tour and a WTA 1000 tournament on the 2021 WTA Tour.^[1][2]

The 2021 tournament was the 120th men's edition and the 93rd women's edition of the Cincinnati Open and took place at the Lindner Family Tennis Center in Mason, Ohio, a northern suburb of Cincinnati, in the United States, making its return to Ohio for the first time since the 2019 tournament after being held in New York City for 2020 due to the COVID-19 pandemic in the United States. It operated at full spectator capacity as participants were required to have tested negative for COVID-19 or be fully vaccinated.^[3]

• Alexander Zverev def. Andrey Rublev, 6–2, 6–3

• Ashleigh Barty def. Jil Teichmann, 6–3, 6–1

This was Barty's 13th WTA singles title, and fifth of the year.

• Marcel Granollers / Horacio Zeballos def. Steve Johnson / Austin Krajicek, 7–6^(7–5), 7–6^(7–5)

• Samantha Stosur / Zhang Shuai def. Gabriela Dabrowski / Luisa Stefani, 7–5, 6–3

The following were the seeded players. Seedings were based on ATP rankings as of August 9, 2021. Rank and points before were as of August 16, 2021.

For the first time since the ATP Tour resumed from its pandemic suspension in August 2020, ATP rankings points were added and dropped per traditional methodology beginning 23 August 2021 (the rankings after the 2021 Western & Southern Open in Cincinnati). A player's current Western & Southern Open ATP ranking points (the greater from 2019 and 2020) dropped 23 August 2021 and were replaced with points earned by the player at this year's Western & Southern Open. Those new points would stay on a player's breakdown for 52 weeks, dropping 22 August 2022. Players who had Western & Southern Open points in their breakdown and did not compete in this year's event also had their existing Cincinnati ranking points drop on 23 August 2021.^[4]

‡ The player did not qualify for the tournament in 2019 or 2020. Accordingly, points for his 19th best result are deducted instead.
