Kamil Majchrzak was born in Piotrków Trybunalski in 1996. As a junior he won the 2013 US Open boys' doubles with Martin Redlicki and the singles gold at the 2014 Youth Olympic Games in Nanjing. He turned professional in 2013 and spent most of the next decade between the Challenger circuit and the main tour, winning a string of Challenger titles; in 2019 he led Kei Nishikori by two sets at the Australian Open before retiring hurt. He played for Poland at the Tokyo Olympics in 2021 and in the Davis Cup.
In November 2022 he was provisionally suspended after positive tests for prohibited substances. The International Tennis Integrity Agency accepted that a contaminated supplement was the cause and that he had not knowingly or intentionally taken them, and gave him a 13-month ban that ended on 29 December 2023. He returned two days later. In 2025 he reached the fourth round at Wimbledon, and in June 2026 he won his first ATP title on grass at 's-Hertogenbosch, entering the top 50 for the first time.
