Katarzyna Piter (Polish pronunciation: [kataˈʐɨna ˈpitɛr]; born 16 February 1991) is a Polish professional tennis player who specializes in doubles.
On 12 May 2014, she reached her career-high ranking of No. 95 in singles and on 9 June 2025, she achieved her best doubles ranking of No. 49. Piter has won five doubles titles on the WTA Tour and one WTA 125 doubles title, as well as eight singles and 26 doubles titles on the ITF Women's Circuit.

In July 2013, at the Palermo Ladies Open, Piter won her first title on the WTA Tour. She and partner Kristina Mladenovic upset Karolína and Kristýna Plíšková in the final, in a super-tiebreak.[citation needed]
Partnered with Fanny Stollár, she also won the doubles title at the 2023 Budapest Grand Prix, defeating Jessie Aney and Anna Sisková inna champions tiebreak in the final.[1] The pair defended their title in Budapest the following year, beating Anna Danilina and Irina Khromacheva in the final which again went to a deciding champions tiebreak.[2] Piter and Stollár were runners-up in the doubles at the 2024 Guangzhou Open, losing to top seeds Kateřina Siniaková and Zhang Shuai in the final.[3] They also lost in the final at the 2024 Jiangxi Open, this time to Guo Hanyu and Moyuka Uchijima.[4]
Teaming with Mayar Sherif, she won the 2025 Mérida Open, defeating Anna Danilina and Irina Khromacheva in the final.[5] Piter combined with Janice Tjen to claim the 2025 Guangzhou Open, overcoming Eudice Chong and Liang En-shuo in the final which went to a deciding champions tiebreak.[6]
Fed Cup
Piter played 2009 for Poland in the Europe/Africa Zone I of the Fed Cup and helped them qualify for the World Group II Play-offs against Japan. In the round-robin stage, she lost her match against Monica Niculescu of Romania, won against Johanna Larsson of Sweden, beat Dijana Stojić of Bosnia and Herzegovina and paired up with Klaudia Jans to beat the Bosnian pairing. In the first play-off against Great Britain, she lost the first singles match to Elena Baltacha, 4–6, 1–6. Poland, however, won that tie.[7]
