Félix Auger-Aliassime (born August 8, 2000) is a Canadian professional tennis player who currently ranks as the world No. 4 in singles (as of June 8, 2026) and is the top-ranked Canadian man. He has won nine ATP singles titles and one doubles title, and was a key member of Canada's victorious 2022 ATP Cup and Davis Cup teams, also earning a bronze medal in mixed doubles at the 2024 Paris Olympics with Gabriela Dabrowski. Showing early promise, he became the youngest player to win an ATP Challenger match at just 14 years old, and as a junior he won the 2015 US Open boys' doubles title (with Denis Shapovalov) and the 2016 US Open boys' singles title. After breaking through in 2019 with three tour finals, he reached the 2021 US Open semifinals and enjoyed a stellar 2022 with four titles, before a resurgence in 2025 brought three more titles and another US Open semifinal, propelling him into the world's top 5. In 2026, he completed a set of all four major quarterfinals at the French Open, becoming the first Canadian player to achieve this feat. Born in Montreal to a Togolese father and French-Canadian mother, he was named the 2022 Canadian Press athlete of the year.
