This is a list of the main career statistics of professional Czech tennis player Kateřina Siniaková. To date, Siniaková has won five singles and thirty nine doubles titles on the WTA Tour, including twelve Grand Slam titles: Australian Open (2022, 2023, 2025), French Open (2018, 2021, 2024, 2026), Wimbledon Championships (2018, 2022, 2024) and US Open (2022, 2026). Many of these achievements she accomplished alongside alongside countrymate Barbora Krejčíková. By winning the 2022 US Open, she collected all grand slams ("Career Grand Slam"). In the same time, she achieved "Career Golden Slam" and "Career Super Slam", thanks to previously winning gold at the 2020 Summer Tokyo Olympics and 2021 WTA Finals. Achieving all of this alongside Krejčíková, they became the second women's pair (and the third and fourth women overall, after Gigi Fernández and Pam Shriver) to complete this goal.
From 2024, Siniaková did not compete alongside Krejčíková; furthermore, in the following years, 2025 and 2026, she won an additional five Grand Slam titles—one with Coco Gauff (2024 French Open) and four with Taylor Townsend (2024 Wimbledon, 2025 Australian Open, 2026 French Open, and 2026 US Open), with whom she completed the Career Grand Slam for the second time in her career.
Beside Grand Slam success, in doubles she also won the WTA Finals in 2021, ten WTA 1000. The rundown is listed below.
Despite having less success in singles, she still left her mark. Her most significant results are two quarterfinals at the China Open and Wuhan Open in 2018. At Grand Slam tournaments, she reached the round of 16 at the 2019 French Open, where she also defeated world No. 1, Naomi Osaka, to make her biggest win so far. She also became the No. 1 doubles player on 22 October 2018, while she achieved a career-high singles ranking of world No. 31 on the same day.
