Sofia Anna "Sonya" Kenin (born November 14, 1998) is an American professional tennis player. She has a career-high ranking by the WTA of No. 4 in the world, which she achieved on March 9, 2020. She was the 2020 WTA Player of the Year, an award she earned by winning the 2020 Australian Open and finishing runner-up at the 2020 French Open. Kenin has won another four singles and four doubles titles on the WTA Tour, including the 2019 China Open and 2024 Miami Open at the WTA 1000-level with Bethanie Mattek-Sands.
When Kenin was a child, she drew the attention of veteran coach Rick Macci at the age of five and became a celebrity in the tennis community soon after. Coached primarily by her father, Kenin developed into a promising junior player, reaching No. 2 in the world after winning the Orange Bowl at the age of 16 and finishing runner-up in the 2015 US Open girls' singles event the following year. She also won the USTA Girls 18s National Championship during that summer. On the professional tour, Kenin made her debut in the top 100 of the WTA rankings in 2018 as a teenager. She won her first three titles in 2019 and finished the year just outside the top 10. With her title at the 2020 Australian Open, Kenin became the youngest American to win a major women's singles title since Serena Williams in 1999. At the end of the 2019 season, she followed up her Most Improved Player of the Year award by being named the WTA Player of the Year of 2020.
